More cover up BS. Two pieces of steel (or any material) don't become one just because there's no oxygen. FFS they think we will believe this sh!t.

Thought you might have gone to "how to weld in space"... bearing in mind, there would be no need for a shielding gas, but how would the arc behave? The weld pool? You missed an opportunity... :-)

That's cool I didn't know his helmet attached on his suit had a bering at the neck so he could turn his head. Why don't they do that today? Their head is like in a giant fish bowl. I guess in the Gemini days their helmets fit against their head. Cool I never knew that 😳 I'm just being a jerk. I freaking love the channel. 👍🏻 Be safe and keep the knowledge flowing.

Gage blocks svfrom.info/history/video/l8WsmGqz1rWIhdg Will Gauge Blocks Stick In Vacuum? svfrom.info/history/video/mrF-qovDyM-EgdC1roperly wrung blocks may withstand a 300 N (67 lbf) pull. Surface tension from oil and water vapor that is present between the blocks Molecular attraction that occurs when two very flat surfaces are brought into contact; this force causes gauge blocks to adhere even without surface lubricants, and in a vacuum It is believed that the last two sources are the most significant. en.wikipedia.org/wiki/Gauge_block
