MATERIALS

1, Paper

2, Pencil

3, Scissors

4, Glue

5, Alka-Seltzer tablets

7, Empty film canister

STEP 1:

Design your rocket, drawing it on paper. A simple cylinder, nose cone, and a pair of fins will suffice. It should stand around 6 inches (15 cm) tall and be approximately 1½ inches (3.75 cm) in diameter.

STEP 2:

Cut out your rocket components (cylinder, nose cone, and fins) and glue them together.

STEP 3:

Open the film canister and drop one-half of an Alka-Seltzer tablet into it.

STEP 4:

Fill the canister half full of water and snap the canister cap into place. Slide the rocket over the cap, place the assembly cap-down, and get back. Watch the rocket blast off.
