My brother went through a brief Star Trek: TNG phase and had one of these transporter toys:
It was clunky but sturdy, about as big around as a frisbee. When you hit the button, the light would go bright-dim-bright and it would play that "beaming" sound effect.
He had it in a toy chest along with just about everything he'd ever stolen from me (gum, VHS tapes, various other important kid shit). I would sneak in to recover my stolen items when he was away. I found the toy on its side and became curious as to whether the batteries still worked. I held it up, hit the button, and when the lights stopped flashing there was a gigantic fucking wolf spider in the chamber. It scared the bejesus out of me, and I dropped the thing and ran.
We lived out in the woods and wolf spiders were a common sight in our house. One also climbed out of a typewriter when I was doing a report, and that did it for me and typewriters.
