Similar to leaving cookies out for Santa Claus on Christmas Eve, making a leprechaun trap is a fun holiday tradition to observe with your kids when St. Patrick’s Day rolls around. If you need some leprechaun trap ideas for when your kid's teacher sends your child home with an assignment to create one, or if you are just looking for a fun project to do with your little ones, there are all kinds of effective traps that are sure to lure in an unassuming leprechaun.
Now why would you even want to trap a leprechaun? For the gold, of course. And the process of building a trap is a pretty awesome way to get your kid's imagination flowing. You can let them get as elaborate as they want, and depending on the kind of trap you create, it's an opportunity to highlight some of the STEAM fields — science, technology, engineering, art, and math) — in the building process.
To make a working trap, you'll essentially need some "gold" candy, some sort of rainbow, and a means of trapping the leprechaun (such as a hole for them to fall into or a mechanism to fall onto them). Once you capture your leprechaun (if you do), make sure you release them pretty soon after they tell you where the gold’s at.
