Some inventions may have sounded cool in theory, but in practice, they only turned out to be good for a laugh! Whether or not they were very popular people did actually buy them.

Here are 7 of the funniest, most useless inventions ever:

The USB Fridge:



This device fits only a single canned beverage at a time. All you have to do is plug it in via a USB port and then wait for the cooler pad to chill your drink. A common complaint about it though was the noise created by such a small device. Was it worth the wait for something powered by secondary electricity to chill a single drink?

The steering wheel laptop desk:



This portable desk would fit securely to your steering wheel giving you a small desk area to work on while you drive. This raises so many questions, but the most important one seems so obvious. What about safety? First of all, consider the airbag? But also, what about the important part of driving – watching the road? This contraption was set up for failure from the start!

Motorized ice cream cone:



This is a plastic device that slowly spins your ice cream, which is placed in the top “bowl area”. I guess the idea was that you don’t have to go through the effort of actually manually twisting your ice cream cone while you lick it. Utterly useless.

Radio / Toaster:



This is a radio and toaster in one. Cool idea in theory, but why would you buy it? There’s not much else to say about this one.

Electronic Bubble Wrap Keychain:



A pocket-sized gadget with 8 bubble buttons that can pop over and over. I can understand why this one would be cool for about 5 minutes, but then what?

Instacloth Towelette Tablets:



This one isn’t too bad. The idea is actually very handy. You can buy a pack of 32 tablets each of which will turn into a towelette when placed in just a splash of water. It’s catered for long car trips. The only reason it’s useless is because now we can buy cheap packs of wet wipes which are basically the same thing, but easier to use.

To-go Dog Travel Bowls:



Do you have a long road trip with your dog in the back seat? Well here’s your solution to keeping them hydrated! This dog bowl clips on to the space between the passenger and driver’s seat and hangs there ready for your dog to drink from anytime. If I put it that way, it sounds really useful, right? But, no road in the world is so smooth that you can have an open bowl of water that won’t spill. It just can’t work. What about braking and turning? The water is just going to spill so I deem this good idea, useless.
