Hint: try sand-blasting the glass parts, where you want them to bond to the resin. This allows a much firmer bond! GREAT WORK!!! Another EXCELLENT video from D&D!!!!

As the air inside cools you will end up with a vacuum. You can almost create what ever vacuum you need using this method easily enough to implode your vase so go gentle to start with. A little bit of water inside acts as a vacuum lost indicator as water will remain vapour in a vacuum but condensate out if you lose it.

Great videos by the way. You have inspired me to try out a few of your ideas on my own home. Keep them up! Hope to see more. 6:09 Nice catch, lol.

I think large sheets of double glass could do it. Consider the coroplast heater with a glass cover watch?v=SF_mEoFRSAQ Thank you for the cool comments:-)

I have seen other videos how solar evacuted tubes work. Could you put a vacuum sealed copper tube into the inner bottle and will it heat up. If so could you use it in cold weather to heat your vehicle while your indoors or have a long enough copper tube, you could attach it to your home like a solar heater. The heated tube would be exposed indoors, the ceiling fans would distribute the heat?? Thanks again, great videos!!!! Hi Dan, thanks so much for your great videos, I can’t get enough of them.

As I understand it, hydrogen, in terms of thermodynamic characteristics, is the substance of choice for use in stirling engines (practical characteristics aside - leakage, reactivity etc). If hydrogen was a heat insulator then I don't believe a stirling engine could operate using hydrogen. Also, there has been comment on using hydrogen as this wouldn’t require a serious vacuum.

He stated that this is unlikely to work any better than the non-half-vacuumed version. sorry, this was supposed to be a comment to purplesan on the next page.
