2. How is the Propulsion
Pop! Activity similar to a rocket? How is it different?
(Answers
will vary.)
A
rocket is similar to this activity because both involve thrust moving
the object through a chemical reaction.
A
rocket is different from this activity because the rocket uses different
fuel, it goes farther and faster, and it is not attached to a string.
It has a cone-shaped top, while the film canister does not.

you added one quarter? Two quarters?
(Answers

With
each quarter added, the "rocket" did not go as far.

your results turned out the way they did?
