#3Wow. I love being reminded of stuff like this. Those cars were so cool.
Edit: I took one of these cars apart as a kid to see how it worked. This site brought back a lot of memories. The little coil spring inside the gear. I have to get my hands on one of these now…

#4This really needs to be done for a GLP-1 auto injecting needle.
Pretty sure it’s the same as an epi-pen as well.
It blows my mind. It’s a disposable, single use device that at the press of button:
1. Inserts the needle in your skin, 2. Slowly presses the plunger until the dose is injected 3. Then retracts the needle with plunger
Three distinct and seemingly opposing motions. With timing. All in a little plastic enclosure. It sure I can think of a toy with that kind of mechanism.

Steve Mould has a great video explaining the mechanism in epi pens

There's an even fancier mechanism with e.g. glucagon pens, where it actually has to rehydrate the freeze dried hormone (glucagon forms aggregations when it sits, has to be mixed fresh)

#9What is the name for the sort of toy car you push in one direction and it continues slowly in that direction? These ones were usually styled as 4x4 vehicles and almost moved like a rock crawler with the 4wd set to low. They could be pushed forward or in reverse (and then would go in reverse).
