Ah, the leprechaun trap – a simple machine that kids make to try to capture elusive, gold-loving tiny leprechauns. It’s kind of like a mouse trap but with a whole lot more rainbows! Leprechaun traps have one purpose: to creatively lure in leprechauns so they’ll take you to their pot of gold coins hidden at the end of the rainbow. Ready to make your own easy leprechaun trap?

Easy Leprechaun trap that uses simple machines

My 9-year-old kid, Liam, designed this simple leprechaun trap himself! My favorite part is his rainbow trap door made from Perler beads and toothpicks. Liam’s leprechaun trap idea is easy and fun to make, and perfect for elementary school kids. So, gather your supplies and let’s get started. Who knows, you may just end up with new pet leprechaun and a whole lot of gold coins this St. Patrick’s Day! ☘️🌈

So what is a leprechaun trap?

A leprechaun trap is a popular STEAM project that kids make as a fun and imaginative way to capture a leprechaun. Building a leprechaun trap teaches kids about simple machines like levers, wheels, pulleys, inclined planes, screws, and wedges. Leprechauns are mythical creatures from Irish folklore often portrayed as mischievous beings who love gold coins. The educational idea behind a leprechaun trap is to have kids build something using simple machines to attract a leprechaun and then prevent it from escaping. Kids typically make leprechaun traps with household items as a fun St. Patrick’s Day craft activity.

VERY IMPORTANT LEGAL DISCLAIMER: Please be advised that making a leprechaun trap is meant to be a creative STEAM experience for kids, and is not intended nor guaranteed to capture real, live leprechauns. 😜

How to make a magical trap door to catch leprechauns

The hallmark of Liam’s leprechaun trap design is his clever trap door. It’s a rainbow circle made from Perler beads with toothpicks on each side, which STEAM fans know is a lever. And the ladder is an inclined plane. Science is fun, peeps!!

I wasn’t surprised that Liam included Perler beads in his design. He’s a huge Perler bead fan. But I was pretty impressed that he turned a Perler beads circle into a lever that swings when leprechauns step onto it to grab the gold coins.

Easy leprechaun trap idea that kids can make themselves

I’ll be honest: I hadn’t heard of leprechaun traps until Liam brought home the assignment from elementary school. And can I be even MORE honest? I was a little worried he’d expect me to design it for him (because I’m kind of a crafter, you know). But I’m happy to say that I was wrong! Liam planned and designed this contraption all by himself with very little help from Mom and Dad other than ironing the Perler bead trap door and helping him cut a cardboard base with a box cutter.

Here’s Liam’s original plan, pre-trap door which was added during the build phase:

My kid's written plan for making a leprechaun trap

Liam calls it the ‘Unlucky Charms’ leprechaun trap because he said it’d be an unlucky day for the Leprechauns who get caught.

Supplies for making an easy leprechaun trap:


How to make a leprechaun trap with a Perler bead rainbow trap door

Step 1: Make the Perler bead rainbow trap door

Use a circle pegboard to make two half rainbows connected with the middle purple center. Have an adult iron the Perler beads so they fuse together. You’ll fill in the two gaps in the next step.

Step 2: Add toothpicks to the trap door to create a lever

Slip some Perler beads onto two toothpicks, no ironing required, then stuff them inside the two empty spaces on the trap. It should fit pretty snuggly, so no glue should be needed.

Step 3: Wrap a cardboard cylinder with green paper

We recycled an empty breadcrumbs cylinder. Pringles chips cans would also work well. Cover the cylinder with colorful paper to make it cuter, then punch two holes at the top using a hole punch.

Step 4: Make a ladder (inclined plane) from pipe cleaners and chopsticks or wooden skewers

Wrap pipe cleaners around two wooden chopsticks or wooden skewers to make steps. And yes, rainbow colors are preferred.

Step 5: Make a base and add rainbows

Cut a large base from a recycled cardboard box. Add paper rainbows to decorate the base, then add the the cylinder on top. You can add some cotton balls for clouds.

Step 6: Load the leprechaun trap with bait

Add fancy gold coins on top of the trap to lure the leprechauns. Then sit back and wait for the leprechauns to arrive.
