Here’s a fun design: a Jaws-branded cologne or perfume bottle. There aren’t too many geeky scents out there, so why not? I imagine this would have a pleasant ocean or sea-breeze scent, as I doubt anyone would want to smell like chum.
Fans of the film will recognize what’s going on here, but for those who don’t know: the cap is the yellow buoy that was tethered to the shark in the film; the hose extending from the pump looks like the rope used for the tether, and it appears to be attached to a shark at the bottom of the bottle.
I went with a conventional bottle design here, otherwise I’d make it look closer to a gas container, with an angled buoy to give it the appearance of being towed by a shark.
