This rocket works by building up pressure inside a film canister. When the pressure inside the film canister reaches the highest point, it will burst open, sending the rocket blasting in the air. The gases that have built up inside the canister will help the rocket propel as it blasts off – just like a real rocket.
- Several sheets of paper
- Plastic film canister
- Clear packing tape
- Alka-Seltzer tablets
- Paper towels
Making your Rocket
- Mold the shape of your rocket with paper. Fold the paper in half; use one half of the paper as the rocket’s body while divide the other half again in two.
- Use one of the quarters for the nose cone and the other quarter for the fins.
- Fold the fin quarter in two and fold it up diagonally. You must now come up with four triangles from your folds.
- Cut along the folded lines to come up with four fins.
- Sketch out a circle and cut around it to have a nose cone.
- Mark the center of the circle to draw two lines from it at a right angle.
- Cut out a quarter from the circle.
- Take a long sheet of paper and tape it to the canister. Make sure the canister will hang down slightly from the paper’s long edge.
- Roll the paper around the body of the canister.
- Tape the fins on the rocket and roll the circular nose into the shape of a cone.
- Tape the nose cone on top of the rocket.
Preparing for Take Off
- Turn the rocket over and fill the canister with a small amount of water.
- Drop the Alka-Seltzer pills in the canister and close the lid tight.
- Let the rocker stand straight (with its nose cone facing up) and you’re ready for take-off.
You may think that only scientists and engineers can make rockets blast off, but you too, can make your very own rocket with just a few materials and ingredients found at home. A real rocket may require several years to make but making home-made rockets just takes a couple of hours.
