Katey's Leprechaun trap

For an assignment at school Katey was asked to make a Leprechaun Trap. She and her Dad put their heads together and this is what they came up with. They cut up the small end of a cone and then placed it cut end in the opening of a bottle. To entice the Leprechaun in to the trap they placed a silver round. She was told that Leprechauns like shiney things and like to break the rules. So she placed a sign that read's Special Treasure Keep out, where the Leprechaun can see it clearly.
