Welcome to /c/tumblr, a place for all your tumblr screenshots and news.

Our Rules:

  1. Keep it civil. We're all people here. Be respectful to one another.

  2. No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.

  3. Must be tumblr related. This one is kind of a given.

  4. Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.

  5. No unnecessary negativity. Just because you don't like a thing doesn't mean that you need to spend the entire comment section complaining about said thing. Just downvote and move on.

No. We were shown why you don't use water in an oil fire. Was a fun practical demo.

My science teacher had a balloon and he lit the string saying “check this out”

The balloon was filled with hydrogen

I don’t think that would be okay to do today

We had a community science day when I was little where they did that. Hydrogen is pretty safe to ignite in a birthday balloon.

I loved it, I’ve never felt such an explosion pressure in my chest!

[–] sem@lemmy.blahaj.zone 4 points 1 month ago (1 children)

It's quite a pop!

They exploded some other balloons too, iirc, but I don't remember too well. I think I was 8.

I wanna get some hydrogen…

My partner would have a heart attack. They can’t even be around a gun shooting or firecrackers, much less that kinda boom! I wouldn’t do that to them.

For me it was less intense than a gun or firework, maybe your balloon was bigger lol.

You can get hydrogen by running electricity through water but I forget how it works.

Oh yeah his balloon was like a nitrous mafia-sized whip it balloon. It was huuuuge!

Also that’s fun! Take out the o… and a H

[–] sem@lemmy.blahaj.zone 2 points 1 month ago

You get O2 and twice as much H2 iirc

At least yours did that outside. Ours did it inside and burnt all the hairs off one arm
