This will probably not be so fun or amazing if you give it to your grandmother and she has a heart attack, but other than that you will be a Christmas hero. Really easy and relatively quick to build and cost $3 at the dollar store plus some stuff I had lying around the house. Also can be used for birthdays and other occasions.
As usual I've embeded the video from my podcast here. I also have embeded video of my son opening the box on christmas morning.
You will need 2 mouse traps for this, I got a package of 4 for $1
A box that will fit the two mousetraps on the bottom. $1
Some mini bows, christmas confetti or anything light and christmasy that won't take an eye out. $2
Some thin strong thread
a small scrap of steel used as a weight
