The other day, I was heating tetrachlorocupric acid in an RBF using a bunsen burner, and at one point it bumped and sent boiling acid three feet into the air and all over my workspace. Some of it hit me, but I was wearing rubber gloves, an apron, and safety goggles since I knew that was a possibility, so I didn't actually get any on my skin.

that was about time lol. if you want a great tip from me, really take your time with it so secure your pieces with clips and clamps, even before you start the reaction. If you're too impatient like I was at first you're gonna have to re-order many pieces :p It breaks so freaking fast when it falls on the ground and the stability is so bad when it is not holded by a clamp, just a little push and it all falls.



Help us build the Sciencemadness Wiki! Every question and tips about amateur chemistry two clicks away, wouldn't that be awesome?! sciencemadness.org/smwiki

How to make a volcano in your lab (a total accident on my part):

Put some methanol in an erlenmeyer flask
Boil the methanol
For added fun, dissolve some iodine in the methanol!




At the end of the day, simulating atoms doesn't beat working with the real things...

scariest thing about methanol is the flames are practically invisible. Had friends hospitalized because of burning MeOH.

Strangely, the methanol didn't ignite, but it did erupt everywhere. The fact that there was dissolved iodine turned the fume hood into a total mess.
