I've come up with another invention that is genius. I just don't know how large the audience is for it, so I'm not going to waste any time developing prototypes until I do a bit of market research. By which I mean: writing this post and seeing if anyone says, "Dude. I NEED one of those."

So here's the invention: A garbage disposal for your bathtub.

Admittedly, I first came up with this idea many, MANY years ago when I witnessed someone barfing in a bathtub. Initially I cringed when I thought of the clean up, and then - problem solver that I am - a lightbulb went off above my head and I thought: If only bathtubs had garbage disposals.

Imagine a world where the switch next to the tub was NOT for jacuzzi jets, but instead a disposal. Tempting, no?

Perhaps you're struggling to see the application for any audience other than the drunken college crowd. Then clearly you haven't used a luxurious bath bomb lately.

Bath bombs - if you're unfamiliar - look like snowballs. Except they're made of powdered bubble bath and they typically fizz and make your water smell nice when you drop them in a bathtub.

They're fabulous. Except that the makers like to press things - like flower petals or grass - into them. I mean, it looks pretty, and it's really quite novel to be taking a lemongrass soak surrounded by grass - or a rose water infusion that swims in rose petals.

But when I drain the water, it looks like I just hosed off the pruning shears in the bathtub. This, my friends, is the moment when a bathtub disposal would come in handy.

Am I onto something? Is this the next Big Thing in home design? Like wine fridges, warming drawers and soft-close drawer glides were 10 years ago?

Or am I - yet again - simply ahead of my time? It's all right - you can tell me I'm a visionary. I won't be offended.
