Alien Scanner Mini
Zoom! Scan for aliens with your super cool magnetic scanner, perfect for sticking to metal or standing on its own!

Do the Stick Test
Try one tile. If it sticks, ask: is it stable, safe, clean, cool, and not important? If yes, proceed with mild chaos.
Safety: Avoid anything hot, sharp, electrical, fragile, dirty, unstable, or likely to annoy another adult.
