Because polystyrene costs more than soap.
My idea: a pressure sensitive pad that goes under the baby’s carseat (or is built in). When there’s weight in the seat, it activates an RF transmitter than connects to a fob on your key chain. If you get more than 10 meters away and there’s still a weight in the car seat, it goes off. No more killing baby because you forgot you were the one dropping him off at daycare.
What if baby is in the car seat, on the roof of the car?
Then it’ll go off as soon as baby rolls off the roof and you drive 30 meters away. Easy peasy.
I guess my facial hair is coarser (or something), because I have never found a disposable that will shave without pulling hairs. Even brand new out of the bag. And the ones with two blades are worse; the first blade will pull on the hair and then the second will slice my face open because the first one was pulling up on my skin.
This. Lube strips on the blades I use are usually 50-75% gone by the time I’m done with the first shave. If I threw away blades immediately after all the lube was gone I’d be homeless from spending money on razor blades.
yep. Gillette Fusion five blade cartridges.
If they put those web things on the handles, there would be another manufacturer war. One would start with ten webs, the next would have twelve, the next would be 15, etc. Even if all the blades were identical they would still do this.
Soon we’d have disposable razors with 25 blades and 300 webs.
Well there is the Spishak Mach 20.
I don’t use it anymore, but a few years ago when I was using Dial bar soap I noticed that they had an oval-shaped depression in the bar that was perfect for holding the little chip of soap left over from the previous bar. I don’t know if they designed it that way or not but it was much easier to use up the old soap than it is with a weird shaped bar like Dove.
I designed (under contract) a similar device for police dogs.
The guy who I designed it for has never been able to market it successfully.
I would have to imagine that, even if you throw the little sliver of soap away (which many people do not), it would have to be much more environmentally friendly to do so than to throw away a little block of plastic every time.
I did see clear bars of soap once that had a 20-sided die imbedded inside each one. I think the idea was that you give it to your favorite hygienically-challenged geek who would then use the soap regularly in the hopes that they could soon get to the die inside to use with their favorite role-playing game. No idea if this was actually effective :). I tried to come up with a similar idea for anime conventions, but I really couldn’t come up with anything similarly appealing to that demographic, able to be encased in soap without damage, and cheap enough to be financially feasible.
As Robert Heinlein used to say, the answer to any question beginning “Why don’t they…” is almost always “Money.”
Use some metal object to put one scratch on the handle after every shave.
Clark Howard says that if you dry off the blade of a disposable razor after using it, it will last many times longer. I’d try it, but I haven’t shaved since '97. My son-in-law says it works like Clark says.
Anyway, I have seen an ad for computer keyboards with high-contrast large letters on the keys for weak-sighted individuals. Why not just sell a set of stickers as an economy option?
Absolutely. I also use the Gillette Fusion Five and I change it the first of every month.
So in a year, I get 31, 28 (or 29), 31, 30…etc. shaves per blade.
mmm
Last week I bending down to grab something from a hot oven, and I wondered, “Why don’t they hinge home oven doors on the side rather than the bottom? That way you don’t have to bend over the hot interior of the door to get close enough to the racks to get hold of the pan, and you reduce the chance of burning yourself on hot surfaces…”
A mouthwash that has a 30sec count down timer on the lid.
This makes a lot of sense to me. Some commercial ovens have side hinged doors, why not home ovens.
Some smart aleck kid would think it was funny to pretend to shut the door on his mom and give her 2nd degree burns on the side of her face. Or the dog would hit it. Or your floor is crooked and it closes by itself.
It sounds like a good idea but I don’t think it’s safe.
Use the hourglass timer in your Yahtzee game. I have one that lasts about two minutes that I use when I brush my teeth.
