How to Make a Rocket With a Film Canister and Baking Soda

Building the Rocket

• 1

  Roll a sheet of construction paper into a tube around the canister once without its lid. Remove the canister, then trim the excess paper with scissors and secure together with tape.

• 2

  Place the lid on the canister and replace it within the tube so that the underside of the lid is flush with the end of the paper tube, allowing the lid itself to be removed later on.

• 3

  Cut a circle out of a second sheet of construction paper.

• 4

  At any point along the edge of the circle, cut with scissors halfway across to its center.

• 5

  Twist and roll the circle to overlap the "corners" you have created to form a nose cone and hold together with tape.

• 6

  Mount the nose cone to the open end of the paper tube with additional tape.

Launching the Rocket

• 7

  Place 1 teaspoon of baking soda onto two squares of toilet paper.

• 8

  Fold the squares several times into a packet that will fit easily inside the canister.

• 9

  Remove the lid from the canister end of the rocket and fill it halfway with vinegar.

• 10

  Insert the baking soda packet, quickly press the cap onto the canister until it seals and place the rocket on the ground, right side up.
