1. Cut straight up the side of the toilet paper roll.
2. Insert the film canister at one end, making sure the end with the lid sticks
out about 1/8".
3. Tape along one edge of the toilet paper roll onto the film canister. Roll the
toilet paper roll around the canister and tape tightly into place.
4. Cut a circle out of construction paper, cutting a pie-shaped wedge out of the
circle.
5. Roll the paper into a cone shape and tape it onto the other end of the paper
tube. Experiment with different sizes of circles to see if it makes a
difference in how the rocket reacts upon launch.
6. Decorate your rocket with markers, crayons, paints, or stickers.
7. Cut 4 squares out of construction paper to make fins if you want. Tape on to
lower sides of the rocket.
8. Take outside: the rocket, water, Alka-Seltzer tablets, and eye protection.
9. Put on your eye protection.
10. Turn your rocket upside down, remove the lid from the canister, and fill 1/4
full with water. Drop in tablet and IMMEDIATELY replace the lid and set on
the ground. BACK UP!
