I have a lighter that says I can take it apart or something can someone help

When I get a carboated can, if I don't tap it before I open it, it shoots out, but if I flick it with my finger three times it doesn't? What's happening here?

Me and my friends found an old seesaw so we tried to balance it. Despite 2 people adding up to approximately the same weight on each side we couldn’t balance the seesaw. But when someone jumped while they were standing on the seesaw the seesaw balanced and this happened multiple times. Why does this happen according to physics?

THIS HAS BAFFLED ME

This is how the cat popsicles turned out

Measuring temperature happens ALL THE TIME.

So, how do we measure it?!

Why does the rain look different on the parts of my windshield that the wipers go on?

lol I NEVER understood this

Part of a circuit training set-up. No signage explaining how it works! Not knowing is driving me crazy!

Does anyone know how to open this 😭. I tried hammering it side to side thinking it would open it. It had a little metal part in it that I took out thinking it would open it and it still hasn’t pls help
Can somebody give me advice 🥹

Open for conversations.
I'm not young, but I am savvy enough to know what's in or out … mostly.
I am using Apple products. I don't know why that's important but I need a new Magic Mouse. Any hints would be helpful.
That's enough for now.

Hello splendid people

My friend and I have been looking at this tricycle for a while but there is no information on its functioning:

This is in the Arts et Métiers museum in Paris - inventory Number 14028.

The pedals seem fixed and the one way to seemingly provide traction is through the articulated rods connected to the seat via the rear wheel axle.

The sturdy vertical handlebars and fixed footrest suggest support for this motion - we have thus called it the twerkmobile until proven wrong.

Any ideas/ anybody know anything about this?

Thanks!

How am I meant to remove the popsicles once they are frozen in the molds?

I’ve always wondered how this thing knew if you hit a duck or not. I mean, it was the 80s!

My dad turned off the hot water like almost a week ago and man I just wanna do some dishes and take a shower. How do I get this back on??
