A Bone Conduction Toothbrush That Plays Music While You Brush
There are already devices you can bite down on that transmit sound vibrations through your teeth and jaw, allowing you to listen to music without traditional headphones. Some glasses use a similar bone-conduction technology.
So here's the crazy idea…
Why not build that technology directly into a toothbrush?
Imagine brushing your teeth while listening to your favourite songs through vibrations transmitted through your teeth and jaw.
Make your morning routine more fun, turn a boring chore into a mini concert, and maybe even encourage people to brush for the full two or more minutes!
The technology already exists in other forms.

Whenever someone says, "it's always five o'clock somewhere," respond, "well, it's always too late somewhere," then recite the carbon monoxide in the garage hotline number by heart.
Just to be a buzzkill.

Tranquilizers for police
Anesthetics are routinely used to prevent patients from becoming violent on the operating table. If it works for preventing patients undergoing surgery from behaving violently, could it also be delivered by dart gun or blowpipes to suspects for the same purpose?

If my dinner has a second job, it should help pay for itself
Chinese food after work sounded like a good idea. Opened the fortune cookie that came with it and found an ad on the fortune. Who looked at that tiny piece of paper and thought “we could monetize this”? Fine but let me hand it back for a dollar off. If my dinner comes with advertising, I want a cut.

Single-use chairs
Bums can be dirty so sitting on chairs can spread dirtiness cos the muck can get through undies and pants. So let's create and industry, economy and world where it is normal for chairs to be single use only.
Cushions are easy-ish to be single use and these are sometimes used on chairs but not always. Lots of wooden, plastic and metal chairs don't use cushions.
Imagine how many jobs we'll create from single-use chairs! Imagine the technologies we'll develop from researching and developing single use chairs! All environmentally friendly of course! Imagine buying weekly pack of single use chairs just like you would a bag of tomatoes.

Start a men’s haircut trend - ‘the crooked hair piece’
Get a haircut that looks like a bad toupee that is being worn crooked. Maybe dye the hair piece just a slightly bit different shade than the sideburns and sides of head as well.
Just to clarify - there is absolutely nothing wrong with men wearing a hair piece. This is going for a poorly matched, poorly fitted one.

Open a bar called "5 years sober"
Open a bar called "5 Years Sober" you can say to your buddies that you're almost to 5 years sober. Or I'm happy to say I'm now at 5 years sober.
Addiction isn't funny, but sometimes bars have funny names. Right?

What if cars had an aviation-style Minimum Equipment List (MEL)?
After watching this YouTube Short and seeing so much deferred maintenance on the road, I started thinking about how much safer our roads could be if cars had something similar to aviation’s Minimum Equipment List (MEL), after all aviation is the safest mode of transportation.
Having studied aircraft maintenance, I’m familiar with how an MEL specifies which equipment can be inoperative, under what conditions an aircraft can continue operating, and how long repairs can be deferred.
Imagine applying this concept to cars: dangerous brake or steering defects would ground the vehicle, some faults would have strict repair deadlines, and nonessential failures could wait until scheduled maintenance.
But what about people who can’t afford safety-critical repairs? I’d pair this system with an income-based repair assistance program to help eligible owners pay for essential repairs, ensuring financial hardship doesn’t force them to drive unsafe vehicles.
Obviously, cars aren’t aircraft, and implementation would have its challenges. Still, why not combine clear safety requirements with financial assistance?
Would this improve road safety, or would the costs and enforcement challenges outweigh the benefits?

Laptop batteries to go up to 125%
Batteries last longer if you only charge them up to 80%, but who wants a battery that's only 80% full? Make that the new 100%, and then, if you really need the juice, you can crank it all the way up to 125%!

Actually flag reposts
don't just downvote them, don't comment "repost", don't just scroll by... actually flag them and get the bot banned.
I've got 4 OC posts that I've made that have somehow made it into the pool bots pull from, I've seen each of them reposted with the same title word for word as my original post. The accounts that posted them were obviously bots (most recently an account that made two posts 12 years ago and then reposted my OC after years of inactivity... so its even worse than an account MADE for karma farming, its an old account that got hacked). I flagged the posts, theu got taken down, and hopefully the accounts got banned too.
If we want a Reddit thats not COMPLETELY overrun by bots, we gotta use the tools given to us to flag them and get them banned.
