After seeing the vending machine disguise, I reckon this will seem a bit tame, mundane even. Ms. Tsukioka, designer of the vending machine disguise, came up with even MORE wacky ideas. The first is the fire-hydrant bag designed to camouflage children.

See the cute grade-schooler transform himself into a fire hydrant.



This next one, however, is meant for your belongings. If you’re carrying anything important and someone who looks like a mugger crosses your path, simply put your stuff inside the manhole bag, lay it on the ground, and none will be the wiser.

Cool, right?

These ideas are so clever, but I’m thinking one would have to really practice to be able to assemble the disguises quickly; like the way soldiers drill with their weapons. (disassembly, reassembly while being timed)
For the record, it’s a fire extinguisher, not a fire hydrant.
