Build Balloon Powered Cars
But science is not just about the experiences that give magical effects like balloon powered cars. It is also the use of knowledge to solve some of the world’s toughest problems. In the energy crisis today, we are in constant search of the science behind our energy sources.
Where does the power, and how it can be used effectively? Check out some of these great energy issues with their children, balloon powered cars putting in an impressive demonstration of a car in the ultra – efficient compressed air!
What you need:
– Clean, dry half-gallon carton of milk with the top cut off, cut in half along the length of the cardboard
– 4 spools (or substitute your own items to the wheels, such as large bottle caps)
straws
– Balloon (and a few extras, too!)
– Hot glue gun and glue
What you do:
1. For starters, you can decorate the milk carton, balloon powered cars then it will not make the car go faster, make the walk more elegant ! You can use tempera paint to cover the surface on the outside (but not put in a drop of dish soap to the paint card waxy layer on the milk carton) or glue on strips of colored paper and brands of windows and doors with a marker.
Do not worry: Do not drill holes in the milk carton … the only hole is what they do to your ball balloon powered cars.
2. Cutting a hole in the center of the rear of the carton balloon powered cars. This is where the ball will go . ( Start with a small hole … you may have to do later if it does not allow enough air to escape from the ball) balloon powered cars.
3. Placing the open end of the ball through the hole balloon powered cars.
4. Making holes in the sides of the boxes to form straw axes. (Axes are rod-shaped parts of the car straight with wheels). These holes should be near the bottom of the carton balloon powered cars.
5. Glue spreader and through the holes of the glue on the reel to form the wheels balloon powered cars.
6. Now the car is built and ready for testing. Before trying it, however, be sure to explain the principle behind it balloon powered cars. Ask your child to fully inflate the balloon, standing at the end without attach, and then let it go.
What’s going on? (IT zips around the room until the air is completely deflated. This is because when the air comes out, balloon powered cars pushing the ball with equal force in the opposite direction. Powers gas ball movement. This is the principle behind the car as well). Ask your child to predict what will happen when the balloon is inflated in the car, and let him go balloon powered cars.
7. Now, try it! Inflate the balloon, but ream. Let it go balloon powered cars. What happened?
Note: You may need to make some adjustments to refine the design of the car, the size of the hole holding the ball, or the ball size balloon powered cars. This is the solution of problems. Encourage your child to keep trying until it works ‐ like all great inventors of the world!
