Balloon Powered Lego Car
The idea is simple: incorporate a balloon into your “car” so that when you blow it up and let it go, the air makes the car roll.
Torch made from coke can and cereal box.
Do we always have to throw everything away?
The torch project below looks at how we can transform materials that we would normally consider as waste, and makes them into a functional everyday product.
Hopefully it shows that we don't always have to go to the shops. An hour or so with some scissors, a coke can and a cereal box and you're pretty much set to go.
What’s needed for this project
Hopefully most of the parts you’ll find in your kitchen cupboards
1 Torch bulb (Standard – NOT threaded)
2 AA (R6) Batteries or 2No C (R14) Batteries. (You will NOT need to make the battery holder if using size C)
1 Large cereal box to make the main body parts (24cm or 91/2" long) Bigger boxes tend to have stronger board
1 Coke can for making the bulb holder and switch mechanism
1 Length of thin parcel wrapping string - Approximately 200 cm or 80 inch for making a grip
1 Small square of cooking tin foil for making a reflector
1 Food colouring to dye the board (Water based are best or coloured inks) Dyes worked better than paints.
1 A small quantity of varnish to seal the cardboard parts. Acrylic varnishes are good.
1 Tube of super glue or other quick drying glue
1 Paint brush
1 Pair of scissors
1 Scalpel or craft knife
1 A paper hole puncher
