Shrink Ray

I saw this out and about yesterday afternoon. I managed to convince my eldest son that I'd just shrunk the traffic cone with my shrink ray magic powers.

Spent the rest of the afternoon discussing why we shouldn't shrink people's houses (would cost a lot to buy the people who's houses we'd shrunk new houses) or cars (what about the people inside?).

Just need to find a full sized traffic cone to complete the scam - maybe a return to my old student ways?
