I have no idea how Santa knew this, but when I was a kid I loved model rockets. Built an X-Wing fighter, a crazy 4-stage one that probably wound up in the Pacific Ocean somewhere, retired an old model X-104 by sending it up and letting the parachute charge finish it off, and somewhat notoriously tried to make a model rocket boat that my mom agreeably, if somewhat naively, brought me to Lake Merritt (in the middle of Oakland, CA if you're unfamiliar) to test out.

Santa has sent us a genuine Estes Tandem X kit, consisting of two rockets, the pad, and the launcher. One rocket is pretty easy to build, the other requires actual making of the rocket. This will be a very fun kid-friendly project in our house, and I can't even begin to overstate my appreciation for Santa's efforts. Thank you!
