Hello,
Question:
1) Took a Stainless Vacuum Thermas and poured boiling hot water into it, 30 seconds later the outside is cold to the touch.
2) Drill a hole and let all the vacuum out.
3) Pour boiling water in, guess what happens in 30 seconds?
4) You are right, the outside is hot
5) Place a pump on the hole and pump out the air to 28HGVAC
6) Pour boiling water in again, guess what happens in 30 seconds?
7) Wrong, the outside is hot!
What do you think the problem is?![]()
