Alright, here’s a prank that’s a little bit of a project and a lot of laughs. Build a “fake gift” box that looks normal but has a hidden spring‑loaded door inside. Use sturdy cardboard or a small piece of plywood for the shell, add a simple latch that you can pull from the outside, and hide a spring that will push a smaller panel up when the latch is released. Paint the outside like a real present, slip in a silly surprise—maybe a rubber chicken, a whoopee cushion, or a little note that says “Gotcha!”—and let the spring do the rest. The key is making the outer box solid so it doesn’t collapse when the inner door pops open. Once you’ve set it up, watch the grin or the shocked “what the heck?”—it’s pure, harmless fun, and it’s definitely worth the effort!

Got it! I’ll tighten up the corners, double‑up the glue, and run a few practice pops before the grand reveal. No one gets a dent in their day—just a lot of giggles. Let’s make this the most unforgettable “whoops” ever!
