Each project includes a list of everything you will need. Most of the items are things you can find around the house, or they are things that are readily available and inexpensive to buy. Be sure to check out the Amazing Science behind the projects and learn the scientific principles involved in each experiment. Watch for this sign ! throughout the book. You may need help from an adult to complete these tasks.

A force is basically a push or a pull. It makes things accelerate—that is, change speed or direction. Without forces, nothing would ever happen because all things have natural inertia. This means they stay stock still until they are forced into moving! Things fall because of the force of gravity. You pick up a drink using the force of your muscles. Discover how to use forces to create motion and blast a rocket into the air, power a superfast dragster, lift a hovercraft, and much more. May the force be with you! You will need: Bouncy balls in different sizes Balloons Thumb tacks 7/-inch (25 mm) 8 steel washers x2 Large and small Long, thin household candle paper clips Tea light Ice pop craft sticks Liquid soap Aluminium drink cans Talcum powder (baby Drink bottles powder) Shallow tray with sports caps Thin craft 6 foam sheet Incense stick Mug Thick nickel- plated wire Cocktail Sheet of stirrer printer paper Old CD or DVD Dowel Wooden chopstick Small wood Elastic band scraps x2 Corrugated cardboard Old plate (not Effervescent paper or plastic) Pins x2 Plastic beaker tablets What tools will I need?

It may not land on the moon, but you’ll Mug be surprised at the whizzing power of Drink bottle with sports cap fizz. So it’s probably best to try this outside—in fact, DO try this outside! 1. Have four tablets ready to use. 2. Fill the bottle with water to the level shown. Complete these next steps as quickly as possible! 3. Break up the tablets 4. With the sports and drop cap pressed down them in the to close it, screw water. the lid on tight. 8
