AIm: to make a marshmallow shooter and work out what forces are acting on it.
Equipment: paper cup, scissors. ballon, marshmallow
method:
- cut out the bottom of the cup.
- cut off the neck of the ballon
- stretch the open end of the balloon over the bottom of the cup
- pull ballon back to the fire marshmallow
result:
I cut myself while trying to cut the bottom of the cup.
the bollon we got was a bit tight so it was harder to put in to the bottom of the cup.
over all it worked out pretty well at the end, m=the marshmallow went pretty far
discussion?:
when the marchamallow was in the cup all the forces ( thrust. firction. gratvity and support) were even as it wasn't moving
