Try this fun rocket made from recycled film
canisters. It's a craft and science experiment
wrapped into one, and it's a perfect Fourth
of July backyard activity!
You will need:
Alka Seltzer tablets, or store brand equivalent
Fuji empty film canisters with lids-the clear white ones
Paper, markers, tape and scissors
Water
The first step is having your child decorate his "rocket".
All tape must be away from the lid area, so the top
won't be obstructed in any way. Work with the cap or
top of the canister at the BOTTOM. He or she can
make a cone to put on the top of the canister, so it
looks like a rocket. Decorate the cone before taping
onto the canister, then tape in place. Another option
is to cut little "fins" for each side of the rocket and
tape in place also.
When the canister is decorated you will be ready to
add the "fuel". This is where the science experiment
comes in. You will need to add water and a part of
the Alka Seltzer tablet to the canister and seal it
with the lid. But how much? Have each person guess
what amounts may work. What happens? (The
correct amount that usually works the best is 1/4
tablet added to the canister 1/4 filled with water. )
Add the tablet and water, put the lid on and place
the rocket CAP DOWN on the ground. Now wait-
in a couple of minutes the rocket will shoot up in the
air from the pressure of the tablet creating gas in the
canister and it becomes a rocket! You can do this
experiment over and over, though your paper may
need to be replaced after awhile.
Note: You can inquire at film developing studios
or store film departments and they may give you a
bag of Fuji canisters. Just ask!
