A friend has one. His girlfriend is scared of sharks, so he surprised her with it at their Halloween party a couple weeks ago. It’s really cool, if a little hard to steer based on the difficulty the people playing with it seemed to be having. That could have been due to the alcohol, though.
The San Jose Sharks will occasionally break out a couple shark-shaped blimps for home games. I’d love to try to sneak one of these into the Tank. Think I can hide a mini helium tank under my shirt?
There’s a … thing … on a track on the underside of the shark, which is weighted. The remote control can make that thing, which doubtless has a name, move forwards or backwards, and that plus the movement of the tail controls the level of the blimp.
