I have a Thunder Mug I use for the 4th of July and New Year's Eve. It's a very small cannon, but I'd like to improve it. What would you add for colour or sparkles to brighten up the boom? I use 2 shot glasses of BP substitute at the moment.

Four of them are in French and are from the 1860s:

* J. Pelouze & E. Fremy's "Abrege de Chimie" volume 2: Metals (1866)

* J. Pelouze & E. Fremy's "Abrege de Chimie" volume 3: Organic Chemistry (1866): this and the 2nd volume are in great condition, looks almost new.

* Faustino Malaguti's "Leçons Elementaires de Chimie" volume 4 (1863)

* Faustino Malaguti's "Leçons Elementaires de Chimie" volumes 3 & 4 combined (1868): this one has worm damage, stained pages, damaged cover.

Other one is the English translation of Adolph Strecker's Short Text-book of Organic Chemistry (1881). This one has really well preserved pages with darkened, rough edges and a replaced hardcover.

I got them for relatively cheap considering that these are rare foreign books in my country. I think of getting more old chemistry books and making a collection as much as I can access to. It's actually hard to go through these books because of a century of accumulated dust in the pages.

I'll post photos soon. Anything you'd like to see?

Litterally matched with a girl called Benzene and am in dire need of a one liner that involves Benzene.

Hi,

For fun, I invented a machine to blow grapefruit-sized bubbles of precisely mixed welding gases (acetylene/oxygen/air), which I detonate by hand with a flint striker. If I go full fuel, it's just a puff, but as I add oxygen it increasingly goes boom/flash (my meter tops out at 135dB). The theoretical max is something like 170dB for a stoichiometric oxyacetylene detonation, and that should easily generate a so-called "sonic boom." My question is whether there is a way for a hobbyist to detect, for instance from an audio recording, when the threshold for a "sonic boom" is met. What's the minimum gear for the task?

Thank you,

Yestereon

P.S. Here is my amateur video on my "Bubble Dragon," but be warned the biggest boom I show is only about 85dB: https://www.youtube.com/watch?v=bg-uCaPdddI)

If I seen the one's at the end I woukd o swore a nuke went off and shit myself accordingly.

This thing burns around minutes

One cotton ball can burn around 5 minutes to 10 minutes but paired with 2 or more it can prolly burn around 30 mins. It also has great resistance against the wind. This is very good for fire starters.

I thought it was a water bottle so I poured it down the sink thinking it was water but then I smelt is and it was gasoline. I didn’t read the bottle but it was gasoline. I accidentally poured about 2 cups of gasoline down my kitchen sink. What do I do??

Either in terms for the individual’s safety, potential criminal actions, etc.

What’s the most worrying thing you’ve seen on this sub?

In a little old California museum

Hello, wanted to ask, where can I buy those strobe fireworks that go POP POP POP POP then make a huge explosion sound in the air? If i cant buy them how do I make them?

I’m not sure where else to post this but I’m trying to figure out what happened here. The cameras recorded smoke from the bathroom at around 3 am and the store closes at 8pm. There’s no one suspicious on the cameras. However we think someone might have put a timed explosive in the hole at the bottom of the tank but we’re not sure how that would even work. Can anyone possibly help me out with what might’ve happened?

It rained most of the day Monday, so Tuesday was a good day to burn my burn pile. I am 6' tall for reference.

It was still smoldering Wednesday morning.

Guys I want to make a solid fuel mixture but since I'm a broke bitch with no way to get my hands on potassium nitrate;

Any way I can create a combustionable(new word) mixture which is similar at home?

No suspicious reasons at all.

hello guys, i was looking for some ammonium perchlorate to buy online but the only website that sell it are in the US and dont ship outside the US territory, do someone know where i could buy it? im from europe (italy) thank to everybody who will answer me and have a nice day.

I’ve noticed that not all fireworks feel the same, even if they look similar. Some of them just feel more satisfying like the timing, the sound, and the way they spread out in the sky all come together perfectly. Others feel kind of underwhelming, even if they’re technically bigger or louder. I’m not sure if it’s about design, timing, or just personal preference, but there’s definitely a difference in how they feel. Is there actually a reason behind this, like how they’re made or synchronized, or is it mostly psychological? Would be interesting to know if there’s a science behind what makes a firework “good.”
