Hey Pandas, What Should Be Invented Already But Hasn't? (Closed)

A variety of lawn grass that grows to 3 1/2 inches then stops.

At any time of the day or night, you can get drinks, sweets, fast food, condoms etc. ... but what if you urgently need pacifiers, drinking bottles or diapers for your baby? There should be self-service machines where you can get stuff like this at any time.

A cube shaped pencil, so your pencil doesn’t role away

I would like a phone that when I dock it, I can turn it into a home phone and pick up another phone connected to the dock in another room. I hate dashing for the phone when it rings. Also this could be a major safety improvement for people at risk for falling, as their "landline" can be installed in places they may fall, such as near the tub

Giant solar powered fans to zone in on specific hot spots for global warming
Bonus for my bro he wants real hoverboards that can fly

Warp drive. Quantum computers

I would like to see more passively active desk builds. The easiest I suppose would be creating an inverted desktop space with apparatus like oculus, in which you can set it so that you can bend and reach for icons and programs. Maybe even an activity setting where you can choose to make it harder or easier on yourself. I feel like this should exist, but Ive only heard of Oculus being used for gaming and its a waste.
You could program the OS to look like a house, and files and programs look like books, or program it to look like some alien spaceship and all the programs look like crystals. Graphic designers could sell templates and mods.

Fake tan in the form of a bath bomb. Just drop it in the water and submerge yourself into the water for a all over glow, kinda like a sheep dip I suppose!!

The cure for tiredness

Two (or more) separate soundtracks on movies (Dialogue can be adjusted separately from music /sfx)

Pen that draws exactly what you're thinking.

A machine that could erase painful & traumatic memories.. especially for crime victims, ptsd patients, etc.. so they can start with their lives again

Neural Firewall Protection and Artificial Telepathy Caller ID. I am constantly receiving messages and cant determine where the EEG Heterodyned brainwaves originate. I would like an option to review the content before granting access to my brain.

Some chemical for underwear that will clean period blood off underwear automatically/faster than peroxide

This is going to sound kinda weird, but... I am a lazy person who likes telling stories. I especially like doing it late at night when my parents aren’t there to bother me. So... some sort of device that you can write with , that doesn’t require you to move (yes I am that lazy) but not like a voice-to-writing kind of thing, because that will wake my parents. Maybe a mind-reading-thingy that transfers your thoughts to words in a google doc or something like that.

I would like a device to roll up my oxygen tubing so I don't stumble when I walk from room to room with my walker. It is a tripping hazard.

Some way to plug learning into your brain. Get an upload, have a month to mull it over, experiment with practical application, ask questions, then another upload. So much time memorizing random facts, when learning to hone imagination, logic, etc would be so much better.

One thing I hate doing is vacuuming but also moping, they should make a robot that sprays cleaner and mops.

A pill you can take to stop hair growing. Then you can have your hair cut and dyed, wax and pluck whatever you want and it will stay the same.

Hmm what about if wireless chargers could actually give you mobility like a charger with a wire does?
