Aim: to find out the acceleration of a marshmallow when catapulted at difference distances
Equipment:
- At least 7 craft sticks (or popsicle sticks)
- 3 rubber bands
- Small marshmallows
- Knife to cut notches on the craft stick *popsicle sticks*
- Milk jug lid
- Glue
Instructions:
- An adult should carefully cut a set of small notches into the end of one pair of craft sticks about ½-1 inch from the end of each stick.
- Stack the other five sticks on top of one another.
- Wrap a rubber band around each end of the pile of the five un-notched sticks.
- Take one of the sticks with the notch in it and squeeze it between the bottom stick in the stack
- and the one above it, sliding it all the way
- through so only the last inch of the notched end is sticking out.
- Take the final stick and place the notched end over the notched end of the other stick.
- Take the final rubber band and wrap it around the notched sticks, making sure the band sets in
- OPTIONAL: Glue a milk jug lid to the end of your launcher to hold your marshmallows in place easier.
- Your catapult is complete!
Measurements:
Just a hint, NOTE: Never launch items towards anyone.
