Liquid Nitrogen is in TC room 371

CO2 (CD75) (75lb cylinders) are in Prep Room 366A

They sell Radnor leak detection solution and dabber bottles but here is a recipe: (see Leak Detection Solution Recipe)

• 946 ml water
• 44.4 ml of dish detergent (Dawn)
• 9.9 ml Glycerol*

The solution becomes more effective if you leave it overnight in an open container. In fact, the longer you leave it, the better the bubbles it produces.

*we've decided glycerin is the same thing as glycerol. It makes the bubbles last longer, which makes them easier to detect
