Bouncy balls!March 31, 2009 | 11:46 PM | 1 comments
Because of the weather on last friday, many people from the chemistry class on 6th hour didn't go to school that day. oppositely, all of us (which is in 2nd hour) didn't absent and we took the quiz already.
as a result, we're ahead of the 6th hour today. so our teacher decided to let us do something fun, which is, making the bouncy ball!
this is my first time doing it so i'm very excited when we're doing it. unfortunately, mine was a failure because it doesn't bounce at all lol
i think the bouncy ball on the picture above look more like a strawberry icecream! haha
in fact, i just put it in the fridge so it's going to strengthen.Here's a list of materials you need to gather to make bouncing polymer balls:
borax (found in the laundry section of the store)
cornstarch (found in the baking section of the store)
white glue (e.g., Elmer's glue - makes an opaque ball) or blue or clear school glue (makes a translucent ball)
warm water
food coloring (optional)
measuring spoons
spoon or craft stick to stir the mixture
2 small plastic cups or other containers for mixing
marking pen
watch with a second hand
metric ruler
zip-lock plastic baggie
Procedure
1. Label one cup 'Borax Solution' and the other cup 'Ball Mixture'.
2. Pour 2 tablespoons warm water and 1/2 teaspoon borax powder into the cup labeled 'Borax Solution'. Stir the mixture to dissolve the borax. Add food coloring, if desired.
3. Pour 1 tablespoon of glue into the cup labeled 'Ball Mixture'. Add 1/2 teaspoon of the borax solution you just made and 1 tablespoon of cornstarch. Do not stir. Allow the ingredients to interact on their own for 10-15 seconds and then stir them together to fully mix. Once the mixture becomes impossible to stir, take it out of the cup and start molding the ball with your hands.
4. The ball will start out sticky and messy, but will solidify as you knead it.
5. Once the ball is less sticky, go ahead and bounce it!
6. You can store your plastic ball in a sealed ziploc bag when you are finished playing with it.
7. Don't eat the materials used to make the ball or the ball itself. Wash your work area, utensils, and hands when you have completed this activity.
