#1 - Build A Balloon-Powered Car
|
Items needed to make car:
- Scissors or utility knife - Tape - 4 Thumb tacks - 1 Large balloon - 1 Toilet paper roll/paper towel roll - 2 Drinking straws - 1 Wooden skewer (dowel) |
1. Use scissors or utility knife to cut toilet paper tube in half.
2. Make 4 holes (or x's)in the cardboard tube in the appropriate places for the axles (make sure each hole lines up to its opposing hole)
3. Cut 1 drinking straw into two pieces (slightly longer than the width of the cardboard tube) and insert into holes for the axle.
4. Cut wooden skewers or dowels into 2 pieces slightly longer than the cut straws.
5. Slide wooden dowels into straws
6. Carefully push thumb tacks into the center of the 4 wheels and push them onto the ends of the wooden dowels.
7. Make a hole (or x) in the top of one end of the roll for the straw that will attach to the balloon.
8. Push the other straw into the balloon and secure the balloon to the straw with tape.
9. Push the straw with balloon attached into the top hole and out the other end of the tube.
10. You can now blow up your balloon (pinching the straw when you're done to keep in the air), place the car on the ground or flat surface, let go of the straw and (hopefully) watch your car go!
