Description

This bouncing ball kit is perfect for any scientist looking to have some fun. With just water and the included instructions, you can create your own bouncing ball in no time. Perfect for a rainy day or a party game, this kit is sure to keep everyone entertained.

What to do

Put a packet of powder into a shallow dish. Cover with water. Wait 10 seconds then scoop out the powder with your hands and roll into aball. Lay on a dry surface 5 minutes to dry out. Keep in a zip-lock bag when not using theball.

What Happens

When the powder mixes with water, it starts a reaction that hooks the powders molecules together. Its these liked polymers that make theballsolid and allow it to bounce.

How much do I bounce?

What to do

Stick a ruler against a vertical surface. Drop theballfrom the 25cm mark and see how high it bounces back up to. Try it again at different heights and see what difference it makes.

What Happens

The higher the starting height of theball, the higher theballspotentialenergy. The earths gravity needs time toaccelerate,or speed up, theballwhen you let go of it, the longer an object falls, the faster it gets. When theballis dropped the potential energy turns intokinetic energy. The faster an object moves, the higher its kinetic energy. When theballhits the ground, the kinetic energy goes into theballand giving it the force to bounce back up.
