My oldest son came home with a school project two years ago to build a Leprechaun trap. It was a creative expression exercise. He was supposed to create a plan, write a description of how to execute the plan and then build it (sounds like Instructables). In classic manner for our house we created the trap in the evening before it was due. We used a cardboard box, and some mousetrap parts. It was very basic but effective. That night we set the trap to see if it worked. Low and behold we were almost successful. Upon waking up the next morning he found that the trap had been sprung and there were a few strands of green fabric caught in the trap!! He was disappointed that we did not catch one, but he was beyond ecstatic that the theory was good and he so close to success. His enthusiasm had an interesting impact on his day at school too. When the time came to review the projects, his teacher explained the history of Leprechauns and their fictitious background. Of course he had to correct his teacher. But, he was brimming with confidence and also able to provide her with the demonstration of his built trap and showed the whole class proof with the fibers. She we very impressed and backed down. She let the class know that maybe he had made a meaningful discovery.
Needless to say that my younger son has been waiting two years to build his trap. He carefully planned his design (I gave him a few pointers to make it more effective). Then we built it. When I say we, I want to make sure you look closely at the pictures. He drilled every hole, screwed in every screw and did all finish work on this project. This is truly his Instructable. I was merely along as a consultant and assistant to his efforts. He is confident you will like his design and he is convinced we will be successful in catching a real Leprechaun this year. Please watch the video at the end.
Parents and Teachers, this is a great educational instructable. It allows you to teach all about critical thinking and problem solving. They get to create a theory of what method will work best. They get to work through the challenges of building from their design. The best part is they get to see if their design actually works when all said and done. Along the way the get to use a large variety of tools and supplies. In this one project they get an education in Art, Carpentry, Science, Physics, Cultures, Folklore, Recycling, Humor (Leprechauns make fun of you when you do not catch them), and Forensics.
Note: This is an "Extreme" Leprechaun trap because it has superior strength and lightning fast spring action. EXTREME measures needed to capture EXTREMELY sneaky and crafty Leprechauns.
