How To Make Homemade Silly String

Silly string or ribbon spray is a polymer foam that shoots out of a can as colored string. The stuff you buy in a can is an acrylate polymer with a surfactant, although most of the can is filled with a propellant to jet the foam out of the container. Since pressurizing a can isnt something most of us can do, homemade silly string uses a simple, forceful chemical reaction to push strings of foam out of a bottle. The reaction is based on the elephant toothpaste chemistry demonstration. Silly String Materials You can get yeast and food coloring at any grocery store. Probably the best place to get the peroxide and the bottle is a beauty supply store. You need at least 30 volume peroxide, which is ten times more concentrated than typical household peroxide solution. jar of active dry yeast30-40 volume hydrogen peroxideplastic bottle with a screw on pointed tipfood coloring Make Silly String Fill the bottle with pointed tip most of the way full with the peroxide solution.Add food coloring, unless you want white string.When you are ready to make the silly string, add a spoonful of yeast to the bottle and quickly cap it. When the yeast and peroxide react, the resulting foam builds up pressure quickly, so if you dont cap the bottle right away, it will be hard to do it later.Shake the bottle to activate the foam. Point the bottle away from people, pets, furniture, etc. The peroxide is a strong bleaching agent, so its best to do this project outdoors. Safety Information Hydrogen peroxide is extremely reactive and can burn your eyes and skin, as well as bleach your clothes and hair. Wear safety goggles and gloves when preparing and using homemade silly string. Dont play with the foam or drink it and be sure to wash down the area after your project with lots of water. Glowing Silly String If you substitute fluorescent dye for food coloring, you can make the silly string that will glow brightly under a black light. Alternatively, you can use glow powder, which will glow on its own, although not as brightly because the pigment worked best when it is exposed to bright light beforehand. Fun Fact: Military personnel spray silly string to detect trip wires that could trigger explosives or traps. How Real Silly String Works If you have a way to pressurize a can, you can make your own real silly string. Over the years, the composition of the product has changed to improve its performance and eliminate the CFC originally used to propel the polymer. The original polymer for silly string was polyisobutyl methacrylate, extruded by forcing it through a nozzle with dichlorodifluoromethane (Freon-12). Since the original patent, manufacturers have replaced Freon-12, an ozone-depleted compound, with a more environmentally-friendly chemical.  The surfactant sorbitan trioleate kept the string from being too sticky. So, to make your own real silly string, you need an acrylate that will polymerize  in air, a propellant, and a surfactant. Go for it!

Drama Unit Conflict Essay Example For Students

Drama Unit Conflict Essay This unit is based on the theme about conflict. Its manly about the conflicts of war and the conflicting relationships between the two most important characters in this unit, Billy and Tommy. To me conflict means not getting along with each other resulting each other being violent to each other, mentally or physically. In this unit I show this when Billy and Tommy have been conscripted to go to war. I show them showing there emotions about each other by using a variety of drama techniques such as: slow motion, being abstract, the use of still images, thought tracking and many more. Lesson 1 I started off by brainstorming all the words I would associate with conflict. These are all the words that I chose: I chose these words because I think that conflict has many effects on a person and some of them are the words that I chose above. I chose these words and made a short piece of mime role-play with my group based on these words. I used slow motion at the start of the mime role-play, because it gives a bigger effect and a good way to use facial expression. Also slow motion helped me concentrate more on conflict as it marked the moment of the scene. (Tommy showing his true side to how he feels about Billy). I also used thought tracking. I think this is the best technique to use when working with the theme, conflict. Because while using thought tracking I felt as if I was with conflict with someone, and I thought of the line I will get you back for this. This line made me think of revenge. I think it links very well with conflict because then I can show the true side of the conflicting emotions that a character feels about another. (Billy and Tommy). In this short piece of mime my facial expressions were of a happy person, because my partner (Ameen) who played Tommy felt that Billy was everything to him. This made me feel happy for him. However when I and my partner used thought tracking, Tommy and Billy felt different about each other and this changed our emotions from love to hatred. By now Tommy and Billy were showing each other there conflicting personalities to each other. They werent the same character as I started off them to be. I had to do a short piece of work, showing four linked still images on Tommy and Billys personalities. In this short piece of work I chose images of both characters, when they were young, what they used to do in the childhood. In this scene I used a varied composition of facial expression. In Image 1, I chose the image of being blood brothers. I chose this image because it shows Billy and Tommys love for each other. I over exaggerated my facial expression because it was a very important moment in there lives. My body language was that I was a shy, because I was playing Billy, who is known to be shy. This is because his dad died in the war. The images that were showed were based on physical, social and mental emotions. As I was playing Billy I had very much to say. This is because I used the idea of thought tracking with my group. I think that this worked really well because thought tracking controls a persons mind and his emotions and also sends the message to the audience in a very strong way. I used the use of slow motion in our piece to link the four images as I marked the moment in each image of the emotion that was being expressed. The words that were most important in our piece were from the first image were Billy and Tommy said Together Forever. This shows the audience that the characters mean a lot to each other and the depthless of their love and friendship. Lesson 2 Turning from a man to a solider. The turning point for both of these characters lives. .uac2c6402d3f178d34d0a36519f41040c , .uac2c6402d3f178d34d0a36519f41040c .postImageUrl , .uac2c6402d3f178d34d0a36519f41040c .centered-text-area { min-height: 80px; position: relative; } .uac2c6402d3f178d34d0a36519f41040c , .uac2c6402d3f178d34d0a36519f41040c:hover , .uac2c6402d3f178d34d0a36519f41040c:visited , .uac2c6402d3f178d34d0a36519f41040c:active { border:0!important; } .uac2c6402d3f178d34d0a36519f41040c .clearfix:after { content: ""; display: table; clear: both; } .uac2c6402d3f178d34d0a36519f41040c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uac2c6402d3f178d34d0a36519f41040c:active , .uac2c6402d3f178d34d0a36519f41040c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uac2c6402d3f178d34d0a36519f41040c .centered-text-area { width: 100%; position: relative ; } .uac2c6402d3f178d34d0a36519f41040c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uac2c6402d3f178d34d0a36519f41040c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uac2c6402d3f178d34d0a36519f41040c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uac2c6402d3f178d34d0a36519f41040c:hover .ctaButton { background-color: #34495E!important; } .uac2c6402d3f178d34d0a36519f41040c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uac2c6402d3f178d34d0a36519f41040c .uac2c6402d3f178d34d0a36519f41040c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uac2c6402d3f178d34d0a36519f41040c:after { content: ""; display: block; clear: both; } READ: The death scene in Romeo and Juliet EssayIn 1914 every man between the ages of 18-41 had to be conscripted and go to war. This included both Billy and Tommy. Both of these characters have different opinion on going to war. Billy doesnt want to go to the war because his dad died in the war and his mother would be scared to lose another member of the family. However Tommy wants to go to the war because his dad was in a war and he survived in it. Tommy believes that if he goes to the war he will make his dad proud and his country. So did many other Billy and Tommys. In this lesson I had to use spontaneous improvisation to explore how Billy and Tommys attitudes were to conscri ption. I started off with a still image and discussed how we were going to do the spontaneous improvisation for 1-2 minutes. This is what I showed. My partner for the still image was Ameen. He played the character Tommy and I played Billy. Tommys image was of a figure that was proud and had just won something. His status and body language was high and positive. On the other hand, Billy showed a negative attitude. When he received the news his facial expression showed a man who feared something would happen to him. I dont want to go to the war. I dont want to turn out like my dad! This is the line that I kept on saying with fear. I was scared to go to the war. In the spontaneous improvisation different groups showed different ways/ideas of how Billy and Tommy felt and dealt with being conscripted. The group that I liked and stood out for me were Group 2 (Lola, Jack, Tahir, Christina and Anthony). They used a multitude of techniques which included spontaneous improvisation, facial expression and split screen. They clearly showed how Billy and Tommy felt about conscription and did most of the scene in Unison. This made it very clear to the audience exactly what they were trying to show.

Law regarding non fatal offences evaluation free essay sample

The law regarding non-fatal offences was described by the law commission as ‘inefficient as a vehicle for controlling justice where many aspects of the law are still obscure and its application erratic’. Furthermore professor J C smith described it as a ‘rag bag of offe3nces with no attempt to introduce consistency as to substance or form’. The first issue with the law on non-fatal offences is the language; firstly the definitions of key phrases are not defined in statute but rather rely on case law examples. For example the law regarding GBH is constantly evolving as shown in the case of R v Dica concerning the transmission of biological GBH however this is not illustrated in statute. The language is also seen as outdated, badly drafted and inconsistent; for example the use of the word maliciously in GBH implies wickedness on behalf of the defendant however this is not always the case in regard to the defendant’s mens rea. We will write a custom essay sample on Law regarding non fatal offences evaluation or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The use of the word ‘assault’ although to those versed in law will know it as ‘causing the victim to apprehend immediate unlawful violence’ to the lay person implies a level of physicality to the act where this would refer a ‘common assault’ or actual bodily harm involving either an assault or battery along with more actual bodily harm. Reform of these issues was proposed by the law commission in regard to replacing the terms used within each offence so that they were clearly defined in statute and no longer relying on case law, with new forms of violence such as those shown in R v Dica to be included and updated. The second issue of non-fatal offences is the hierarchy of sentencing; currently the law stands that assault and battery receive a maximum 6 months imprisonmen  having a possible sentence of life. However as s. 20 requires far worse injuries than ABH it seems illogical to place them at the same sentence when one is far more serious in terms of both actus reus and mens rea. S. 18 on the other hand jumps straight to a life sentence for simply a more direct intention that s. 20. Reform of this issue follows the theory of increasing the sentence threshold for s. 20 from 5 to 7 years with the current sentence for s. 18 being sufficient. Lastly the issue of constructive intent in regard to both s. 47 and s. 20 are an issue; s. 47 ABH requires only intention or recklessness as to assault or battery. S. 20 requires only recklessness as to ‘some harm’. In both cases the fact that theoretically the maximum sentence of 5 years could be applied for an act with the defendant only had the basic mens rea towards seems unjust and runs counter to a defendant’s criminal liability that they should be liable only to the amount of fault they possess. Reform of this matter was laid out in the draft bill by the law commission in 1998 that the harm intended of foreseen must correspond to the offence committed contrary to the mens rea principles in Roberts and Mowatt. A person will only be held liable of actual bodily harm if the possess the prior knowledge that their actions would cause injury not just the assault or battery. Similarly a person must have known that their actions would recklessly or intentionally cause serious harm not just some harm in relation to s. 20
