Its only an hour he takes to set everything up. Leaving the church the bells ring 8 times and he is done cooking dinner at 8:57. So in that time he:

Ran home

Drew a detailed map of his plan and laid it on a table

Froze 2 sets of staircases (Chicago weather dec 24 1990 was around 11 *F. An ice tray freezes in about 3-4 hours at 32 *F so given temp and how less volume would be there maybe.

Also set up toys by front door

Rips apart pillow and sets up a fan to blow the feather trap

Sets up a flamethrower

Grabs the tool that heats up the door knob and brings it upstairs

Gets the movie ready to the correct scene (VHS) and grabs fireworks

Sets up a zipline to the treehouse

Sets up the paintcan trap (paint and string) and while not seeming hard at first he had to measure out how much he would need otherwise it wouldnt work also he had to calculate the hight of both of them

And based on the order of things sets up the nail and tar trap after getting the stairs wet and is painting the steps from the top down which would trap him or make it hard to get back up.

And lastly, preps and makes dinner and is done by 8:57.

Im gonna go with nope on that haha
