- Stretch the open end of the balloon over the bottom of the cup.
- Place marshmallow in the cup.
- Pull balloon back to fire marshmallow.
Results:
Discussion:
- when the marshmallow was in the cup all the forces( thrust,friction,gravity and support) were even as it wasn't moving.
- as soon as it leaves the cup then the thrust force was greater as it speed up.
-
Conclusion: it works.
Should you change anything? no
