Weirdest Gadgets of CES 2025 So Far

Not all devices can be vacuum shoes, but most of the weirdest gadgets shown at CES every year are mouth-based; that's just science. In 2025, we've got a smart toothbrush for children that personally gives me the spooks, and that's just to start. Also, there's a spoon that gives you a mild electric jolt to simulate salt -- we're big fans of pumping electricity into our wet gobs around here!

Read on for the strangest things we've seen from the show floor at the dawn the second day of CES.

I don't usually get press releases for gadgets I really hate sent directly to me. But the moment I opened the email for this Willo device, I couldn't help but repeat, No! No! No!

See, apparently you can't trust kids and their little hands. Robots can do it better! With the Willo AutoFlo Plus, kids chomp down on the horse-bit thing with the brushes on it and then have to stand there with the handle dangling out as the machine whirs away on their teeth. It's like an espresso machine, but instead it's your child's face. The device is smart, and it has an app, but seriously, who do I have to call about this?

The "Electric Salt" sounds like a dance, but this kind involves the fleshy muscle found in the mouths of most vertebrates -- because this is CES. The Kirin Electric Salt Spoon changes the salt ions with scientistics, to give your tongue more of that salty taste it loves, with marginally less sodium.

Our intrepid tester, Jon Reed, thought the difference was subtle but still noticeable. Nothing like paying for a gadget that might work if only you believe in it hard enough! The Kirin Electric Salt Spoon is the spirit of Christmas for the condiment world. 

R2D3 (see what they did there?) is a "Roomba on steroids," according to its founders. CNET sister site Mashable says that its only demonstrable ability at the show was opening soda cans. For $40,000.

To me, it looks like a fairground skill tester. Hit the target and see if you can ring the bell. Give me that huge mallet; I know just what to do.   

I still can't decide whether this next gadget is brilliant or very, very silly. Add-on screens for your laptop have been around for years, and they're useful for travelers who need to do presentations on the go. The big "huh?" with the FlipGo Horizon, though, is the weight. Strapping a pair of these to your 3-pound Macbook Air adds an extra 5 to 8 (!) pounds, and it kinda reminds me of Icarus while it's doing it. Want to look like a l33t gamer in your local coffee shop, even if you're just tabulating figures? The FlipGo Horizon gives you two front-row tickets to StaresTown!
