1/4 of an Alka Seltzer tablet Warm water
1. Fill the film canister 1/2 full with warm water.
2. Drop in 1/4 tablet of Alka Seltzer - no more.
3. Snap the lid tightly into the canister, turn it over on a hard surface, and stand back! The sodium bicarbonate will make the canister launch into the air. If you vary the temperature of the water, your rocket will shoot to different heights. The warmer the water, the higher it will go.
4. If you want to make a rocket launch pad, cut three slits about 1 inch high in the bottom of a toilet paper tube. Bend the slits so you can tape them to a paper plate. You might want to decorate your plate and tube first.
5.
When you are ready to launch your rocket, drop the prepared film canister into the toilet paper tube and stand back!

What You'll Need
Modelling clay
Set up a work area with newspaper, or have a surface that can get wet. This project can get messy!
Model your volcano out of brown and green modelling clay. You can use red clay around the rim of the volcano to make it look like flowing red-hot lava. Scoop out a hole at the top of the volcano and stir in 1 tablespoon of baking soda, a few drops of red food colouring, and a few drops of liquid dishwashing detergent.
When you're ready for the volcano to erupt, pour in 1/4 cup of vinegar and stand back!

What You'll Need
A bowl of water
1. Put a few matchsticks in a bowl of water.
2. Drop a small amount of dish soap into the centre of the bowl and watch the matches shoot across the surface of the water like power boats!
3. Clean out the bowl and refill it with water and the matchsticks.
4. Lower the sugar cube into the bowl and watch the matches float towards it!
The soap gives off an oily film that rushes outwards and pushes the matches away, while the sugar is porous and sucks water inwards, pulling the matches towards it.

Empty soda or water bottle
1. Tear the paper towel in half. Take one half and tear it in half again. You will use one of these smaller squares as your wrapper.
2. Place about a tablespoon of baking soda on your wrapper. Fold it up and twist the ends closed so that the baking soda is neatly inside.
3. Pour about 1/4 cup of vinegar into your bottle, and add the wrapper of baking soda.
4. Quickly place the balloon securely over the top of the bottle and watch the balloon blow up by itself!
Note:-
This experiment works because the vinegar and baking soda mixed together produce a gas which fills the bottle and the balloon. The paper towel is used to protect the baking soda for a short period of time while the balloon gets placed on the bottle.

What You'll Need Vinegar
Tired of those brown pennies? How about green ones!
1. Fold the paper towel in half and in half again.
2. Place the paper towel on the dish and pour vinegar on it until it is completely wet.
3. Put the pennies on top of the wet paper towel and wait 24 hours.
4. The pennies turn green!

White flowers
1. Put a white carnation or daisy in a vase with 1/2 cup of water.
2. Mix 10 or more drops of food colouring into the water.
3. Leave the flower overnight, and you'll see the petals change colours. If you leave the flower in the coloured water longer, more colours will fill the petals.
The food colouring travels up through the stem by capillary action and leaks into the flower's petals. If you look closely at the petals you can see the path that the food colour and water travel.
I guess that proves the saying "You are what you eat!"
