Instructions
Select a mousetrap that is small enough that children can work the spring mechanism. Larger traps may snap down on a child's fingers and harm them; smaller traps should pose no problem for a child.
Remove the mousetrap trigger and trigger arm from the trap with a pair of pliers.
Insert the handle of the spoon under the swing arm of the mousetrap so that the bowl of the spoon is face down. Push the spoon toward the trap so that the end of the handle almost touches the spring of the mechanism.
Tape the spoon to the swinging arm of the trap with electrical tape.
Carefully pull the swinging arm of the trap upright. Wrap tape completely around the swinging arm of the mechanism and the spoon.
Pull the swinging arm back so that the spoon's bowl faces upright. Place a projectile such as a cotton ball, marshmallow or grape into the bowl. Pull your hand back and allow the arm to swing freely to launch the projectile.
