Sure! Grab a large cardboard box, cut it into a conical shape, reinforce the seams with duct tape, and bolt a foam rocket engine onto the base. Paint the whole thing with glow‑in‑the‑dark paint, but add a second layer of reflective tape in the upper half to mimic solar panels. Attach a small LED flashlight inside the nosecone and connect it to a 9V battery with a quick‑connect switch. When you press the switch, the flashlight lights up, the rocket glows, and you can shoot it a few meters—just enough to “scout” the backyard for any lurking extraterrestrials. Don’t forget to program a simple timer so the engine cuts off after a few seconds and you’re safe from runaway rockets!

Totally! Stick the battery in a snug pocket with some Velcro, maybe even a rubber band loop, so it stays put. The cardboard pilot can be a mini‑fig with a paper clip antenna—just the right size to look like an intergalactic explorer. Once it launches, watch the glow paint map a starlit path across the grass. If you see any flickering shadows, you just discovered a UFO— or maybe just a cat. Either way, it's a win!
