Add a BANG to your next science or chemistry lesson with these pair of Hand Blasters. It's science you can hear, smell and see. Throw one Ball up in the air and catch it in your hand as you hold the second ball. You'll hear a loud CRACK! BANG! as they crash together. The secret lies in the coating of the balls. They are coated with potassium chlorate, glue, sulfur and powdered glass. As they crash together, a chemical reaction occurs between the potassium chlorate and sulfur resulting in a release of energy in the form of heat and sound.  A great lesson in exothermic reactions and friction demonstrations.
Non-flammable and safety tested

 What you'll get:

• 1 Pair of Hand Blasters in a box. Bangs over 400 times!
• Safety tested and Non-Flammable.

Incredible Science Fun Learning Ideas:

• A great demonstration in exothermic reactions and friction.
• Learn the chemistry behind the reaction and chart the reaction and BANG based on height and other factors.
• Use the hand blasters in a dark room. Put a paper between the two balls as they strike and see what happens.
