SCIENCE EXPERIMENTS
Pocket Rocket
This experiment uses a Vitamin C tablet, warm water and an old film canister. You fill the canister halfway up with warm water, drop a tablet in and quickly close the lid.
How does it work?
Carbon dioxide gas builds up so much pressure it pushes the top off the film canister and launches it into the air. The carbon dioxide gas is made when the tablets hit the water.

Boomerang Can
The boomerang can will roll back to you no matter how hard you push it away from you. You push the can away from you and watch it roll back.
How does it work?
A heavy coin is taped to the middle of an elastic band. Thread the elastic band into the middle of the tube and then tie a knot at each end. When you roll the tube, the weight of the of the coin, twists the elastic band and the can will always roll back to you.

Buzz Box
This experiment uses electrical wire, small buzzer, battery, shoe box and flex.
How does it work?
Electricity cannot travel around the wires in the buzz box unless they are connected in a circuit to both ends of the battery. As soon as you touch the wire loop to the zig zag you make a circuit and the electricity is able to flow.

Oozing Face
This experiment uses hydrogen peroxide and potassium iodide. You mix a bit of hydrogen peroxide with a catalyst called potassium iodide and a small amount of washing up liquid. When they collide they create a big foaming mass. By then putting a container over the top with a couple of holes cut out of it, the foam will then spill through the holes.
How does it work?
The hydrogen peroxide creates a chemical reaction with the potassium iodide – the washing up liquid creates a bigger amount of foam.

Mints and Cola
All you need is a big bottle of fizzy pop and some mints. Carefully open the bottle of pop and put the bottle on a flat surface so that it will not tip over. Unwrap a whole roll of mints. You have to drop all of the Mentos into the bottle at the same time. You can use a tube to help them fall in quickly. Place the tube over the bottle and then tell everyone to stand back!
How does it work?
Fizzy pop is made of falvoured water and sugar. Carbon dioxide is pumped into bottles to make the bubbles. The gas is trapped inside the bottle and will only be released when you open it.
Each mint has thousands of tiny holes all over the surface. These tiny holes are perfect places for carbon dioxide bubbles to form. As soon as the mints hit the drink, bubbles form all over the surface of the mints and expand. The huge bubbles make the gas rush out of the bottle in an incredible blast.
