    One suggestion when you are melting glass, is when you are finished with whatever you are trying to make, whether it be a sealed vessel or blowing glass, is to continue to heat the area you have melted, and slowly move the flame away with providing even heat. This will help prevent cracking or breaking of the glass now being brittle due to uneven stresses within the glass.

    I am curious how you get the contents of the sealed tube after the reaction.

    Random question but I was checking to see if they have coco ichibanya in Thailand and saw that they have opened one in California. Was just wondering if you've been?

    Was this some sort of zeolite or catalyst reaction you were doing in the tube?

    The glasses have neodimium lenses in that filter the sodium flare

    It didn't suck in the atmospheric pressure push it in. :)

    I didn't consider sealing a vacuum flask so easy, but I guess the biggest trick here is making the glassware.
