... liquid nitrogen and ping-pong balls ... dry ice and dish soap
In Cricket terms, that is a "short delivery".....She would be far better bowling a "Yorker" on a Cricket pitch..!!
What is 'Dry Ice' if it isn't chilled nitrogen...??
Been there and done that - mucking around with super chilled nitrogen - Dry ice chilled with Isopropyl Alcohol....gets it down to -75 Deg F.
Dry ice is frozen carbon dioxide.
We used frozen Nitrogen....Nitrogen being inert and DRY...
Used it to "Snap Freeze" aircraft sealants once they had been mixed...we could keep them like that for up to 3 weeks.
Carbon dioxide freezes into a solid at -110 F or -79 C. Nitrogen freezes into a solid at -346 F or -210 C. Carbon dioxide goes directly from a gas to a solid without a liquid phase hence its called dry ice. Nitrogen has a liquid phase before becoming solid so it isn't called dry.
Another contribution to science class ...
... there's some BIG stuff out there !
Okay, science majors - who are these people, and what scientific principle is being demonstrated ?
