It's 1:30am - and kids are still up

It must be summer time. It's 1:30am and I have kids still up wandering around the house. These kids won't sleep. There's only about a month of summer left before the school year starts again in August, and it's going to be a hard transition for the kids, but it's nothing that a glass of ice water can't fix. How you ask? - Let them know you'll be pouring it on them in the morning if they don't get up when you've told them too :) It's amazing what kids can do with the proper motivation :)
