This is a great activity you can do with your kids and at the end of the day you can go to bed thinking "I wonder if they'll need blankets in there?" (Because this will take you all friggin' day)
First you'll want to pick up some Kragle, yes, like in the Lego movie. Is Kragle a real thing? I don't know, you Google it. There's also stuff like Gorilla glue or hot glue if you also want to ensure there are no fingerprints left behind. For the bottom of the cage you can glue a whole bunch of Lego planks to a 3 x 3 wooden board. Once you have those glued and arranged you'll want to build a wall that is 10 Lego's deep and 10 Lego's wide. Tell the kids it's a race to see who can make their wall first, this is a great way to speed up the process, make it fun! (For every kid you have you'll want to double up on the dimensions). Once you do that you'll want to make "bars" by doing a 4 deep and 4 wide and then a space of 6 so you can see in to make sure they are gnawing at anything. At the top, as the lid, you'll want to make planks but triple up. Make a couple hinges and you're kids are good to go. Simply lower your kid in one, put on the lid and turn out the lights. Then turn them on and say "Just kidding!" Then turn them off again, walk away and listen to the endless screams. Makes a great joke for anytime of day.
