GLOVES? You're handling 6M H2SO4 goddamnit, gives me the willies

This is a useless video

Is he making a fookin bomb?

Numerical simulation of the phenomenon: @.

Amazing

Worst video i have ever seen till date.

so... can you explain the science behind why one catalyst is better than the other?

love this video,it's simplified and understandable

Why he plug the flask of the acid?

Hi! We are the students of Jeonnam Science High School in Korea! We have a lot of interest in Chemisty and these days we are conducting a study on bz reaction. We tried to make it in our laboratory, but we have failed all the time. There were so many ways to make it, and we couldn't ensure about them. By chance, we could see the video that you uploaded in KZbin and wanted to ask you HOW DID YOU MAKE THAT REACTION, concentric circles made a beautiful pattern. We found all the materials used, but we're not sure about how much of them are used. [email protected] This is my e-mail and I hope you to have an enough time to give a respond to our message! Have a nice day! lol

Great video! I was looking for different catalysts to use in my experiment. Btw, did you measure the temperature in each cylinder, to see if there was a noticeable difference?

Very useful!

Awesome man, keep it up!! This video helped me a lot!
