Catapult Mouse Trap Offers New Twist On Old Design

Paying homage to the medieval siege weapons of yesteryear, the catapult mouse trap is a fun project to create at home that exemplifies the basics behind the age-old machines.

Their construction, too, will help those involved in the creation learn more about the history of the great weapons of siege warfare while also offering lessons in mathematics and physical science.

Mouse Trap Catapult designs can vary, but the basic principle is the same for these scaled down models – the mouse trap itself does the hurling. In the case of the catapult mouse trap, projectiles, however, are generally small and lightweight – marshmallows or marbles for example.

Basic catapult mouse trap plans call for the use of ordinary materials readily available to anyone and often found in homes or hardware stores. A materials list for the creation of a catapult includes such things as plastic spoons, Popsicle sticks, wooden dowels, rubber bands, string, glue and of course a mouse trap.

Another basic catapult mouse trap design calls for the use of erasers and Popsicle sticks. In this catapult design, the mousetrap’s lever is pulled back and secured with a rubber band, which is fixed around the lever and the base of the trap. One eraser is fastened to the mousetrap with the long end of the eraser against the fulcrum of the trap. The second eraser is placed on top of the first so that the second is slightly above the fulcrum. Tape is then placed around both erasers to nearly complete the design of the catapult mouse trap.

Once this is done, the catapult mouse trap lever is released and brought up so it stands next to the erasers. A Popsicle stick is then taped to the lever so the stick is perpendicular with the lever – this helps support the catapult's arm. Another stick is then taped to the lever so that it is parallel with the lever. This extends the arm of the catapult mouse trap.

A spoon should then be attached to the end of the second stick using a rubber band or tape. This catapult mouse trap will launch very small, lightweight objects. Good items for launch include marshmallows, marbles or bubble gum balls.

Design plans for catapult mouse traps can readily be found online. Plans are even available for sale on such web sites as and plenty of competitions challenge designers to create a better catapult mouse trap.
