Catapult Made Of Popsicle Sticks And Rubber Bands

Physics behind a mini popsicle stick catapult.

Catapult made of popsicle sticks and rubber bands.

It involves moving a load a steel ball or aluminium foil roll in this case around a fulcrum or a pivot. Now take a plastic spoon and attach it to the vertical stick with a rubber band. Take 9 popsicle sticks and secure them with a rubber band on one side then take a popsicle stick place it between some of these vertically and secure the second end. Connect the two triangles with popsicle stick crossbeams on each corner.

Lay the second notched stick on top of the stack and secure the two popsicle sticks together with a rubber band as shown below. To do this you need a hot glue gun and a cap from a water bottle or sports drink bottle. Design this easy catapult with craft sticks a spoon and rubbers bands we first ran into this popsicle stick catapult design at the magic house maker workshop. The catapult behaves as a lever.

The pivoting action is provided by the last junction made by the rubber band on your popsicle sticks as described in the process above. Popsicle sticks 8 rubber bands at least 5 glue plastic bottle cap to hold a cotton ball cotton ball if you do not have any available you can make a small ball by crumbling some paper small open area one square meter will do. If you are having difficult keeping the elastics in place at the end of the v you can put a small notch on either side of the popsicle sticks or glue on a small button see craft stick launchers for a similar application. Make sure each crossbeam is on the same corner of each triangle create the catapult s lever by gluing a bottlecap to the end of the large popsicle stick.

For a simple popsicle stick catapult you will only need a few items. Scissors optional projectiles mini marshmallows gummy bears sparkle balls cheerios or other soft objects work great stack some popsicle sticks we used 7 and use rubber bands to secure both ends of the stack. This popsicle stick catapult design is very similar to the one above except you are replacing the spoon with the bottle cap. The idea is pretty simple and there s lots of variations.

Attach the two sticks with a rubber band on the end so you create a v shape. The simplest catapult to make. It should be a sturdy flat surface such as a table or floor. Create more leverage with your catapult by pushing the stack of popsicle sticks towards the notched ends connected by the rubber band.

The supplies are 10 popsicle sticks a plastic spoon 3 rubber bands. Popsicle sticks 8 10 3 rubber bands.
