Marshmallow Shooter

Hypothesis: I think this activity will be successful and we are be able to make a marshmallow shooter. 

Equipment:

1. 1 clean cup
2. 1 balloon
3. 1 pair of scissors
4. 1 marshmallow

Method:

1. Cut the bottom off the cup with the scissors.
2. Cut the balloon half way along the neck.
3. Stretch the balloon over the bottom of the cup.You may find this a bit tricky to start with, but after making a few it becomes easy.
4. Pop your marshmallow into the cup.
5. Fire the missile by pulling the knotted neck of the balloon back and letting it go. You will be surprised at how far it can travel
6. The open end will fold together when you stretch the balloon, but this will not stop the missile from firing.

Results (Describe what you saw, take a pic/video):

Discussion (What were the energy changes happening,
explain what you saw): This activity has kinetic and elastic energy.
It has elastic energy because while doing this activity we have
to pull the balloon we are making a motion. And it has a kinetic
energy because when we released the balloon the marshmallow
flew away from the cup.

Conclusion (Was your hypothesis correct, did the experiment work?): Our experiment work because once we are done to our experiment and try it to a marshmallow we made it flew away by doing to right step that we have to do. We pull knot that we created to the balloon and release it after that the marshmallow flew away.
