Matter Magic Trick Show

The 6th grade (me) had a matter magic trick show. I was partners with Matteo and we both made a sort of slime substance, they were two different types of slime. I made GAK and Matteo made actual slime. What I did to make GAK was mix borax with water and then add glue to it. my recipe was
1 cup of water
1 cup of white glue (8 floz)
1/2 cup of water
1 teaspoon of borax powder hand soap.
Optional- Food coloring

What to do
1. Make sodium borate by adding 1 tablespoon of 20 Mule Teamรค Borax powder to 1 cup warm water. Stir until all of the powder has dissolved.

2. In a separate container, mix 2 tablespoons glue and 2 tablespoons water. Stir well. (Optional: Add 3 drops of food coloring to the glue/water mixture and stir.)

3. Add 1 tablespoon of the sodium borate to the glue/water mixture.

4. Stir and let sit in the cup for a few minutes.

5. Take it out and play with it!

6. Remember to always store in a clearly marked, sealed bag in the refrigerator.

What we did was everyone set up their stations and then one by one each kindergarten class came in and then two would come to our station and then two kindergarteners would come to our station, we would do the experiment with them and then two new kindergartners would come. Some facts about GAK are that white glue contains millions of long strands of molecules that are like a chain. The chains are able to slip and slide easily and freely over one another, it is like freshly cooked spaghetti. Even tough they can slip around the chains are very long that they interfere with each other and that causes the glue to be thick and dense. Borax, when that is added to the glue two things happen. Number 1, the borax links and brings together the long strands of glue together, it is called cross linking, and number 2, cross linking creates a net-like structure and that is what makes the GAK behave like a solid, but the net like structure also traps the water in between the strands and that trapped water is what makes the GAK behave like a liquid. That concludes that GAK acts like a solid and a liquid. Also if you deiced to make GAK some things that will make it last longer are washing your hands every time before using it, and and when you are not using it to put it in a refrigerator. WARNING: do NOT eat GAK, if you get medical help immediately! Do not throw it in a toilet, do not put on fabric, wood, or vinyl, it may damage them.·
What Else you can do

What happens if you change the amount of sodium borate? What happens to the Gak?

· What if you change the amount of glue? What happens to the properties of the Gak?

· What if you use more or less water? What happens to the properties of the Gak?

· Use coins or small objects to make imprints in the Gak. Do these imprints last?

· What happens to Gak in the refrigerator? What happens if you freeze it?

Neon, when heat is added first the molecules, but only for a short period of time, move together, then they start speeding up and then they separate and when heat is taken away there is less energy and the molecules start to come together and then they freeze and still move, but as one. For Argon when heat is added they move as one and then they stay close together and start bouncing off each other and then it becomes a mad house when they start flying away when more heat is added. When heat is taken away from Argon they move left to right but the molecules stay together and then they slowly start to calm down and start to vibrate and eventually it even stops vibrating! One way to describe the molecules in oxygen is that when heat is added it looks like a huge group of friends (molecules), and then a fight (heat), happens and they all split into two friends (compounds) at a time and just burst off playing (spreading apart) in all directions. Water is a mixture that when heat is added to it, it just starts spinning and spreading apart. There are differences in these liquids, and those are the densities and the density tells you how long it will take to freeze and how long it will take to turn into a gas.

The more density the longer it takes for both of these process to happen. When i close the lid on the neon it spreads and then the top comes off. With Argon the more I move the lid closer the faster the molecules start to move and then the lid eventually comes off and the more Argon that I add the sooner it will pop. With the oxygen it lets me g down almost to the end with the lid, but then it does pop, but the more oxygen I add the less it lets me get closer to the bottom because then it becomes more dense. With the water what happen is that I keep going and I cram the molecules together until they fught so much they cant stand each other and then once again the lid comes off.
