Utility

Plastic sheets

The main use for plastic sheets is making large water bottles - these are functionally identical to large beakers.

Add 30 units each of Welding Fuel, Carbon and Hydrogen to a large beaker.
This combines into Oil. Discard 10 units.
Separate 30 units of Oil, then heat the bottle to 1000* Kelvin until it turns to Ash.
To the remaining Oil, add 10 units Sodium/Water/Chlorine each.
Now, heat the resulting Oil/Table Salt mix to roughly 420°K.
Set the Ash bottle to use 5u amounts and repeatedly use it on the heated Oil/Salt mix.
You now have enough Plastic sheets to make a lot of large bottles!

While not as elegant as smart foam, this one is great for dealing with AI turrets and containing Critter outbreaks.

Make enough Fluorosulfuric Acid and Foaming Agent that you end up with 30u each.
Fill beaker A with 90 units of Iron and insert into the grenade casing.
Put 30u of Fluorosulfuric Acid and Foaming Agent each into beaker B and finish up the grenade.

Want to spruce up the station? Start throwing these grenades everywhere. Same range as the foam version, but doesn't slip people.

Make 50 units of Space Drugs, 50u of Fluorosurfactant and extract 50u of Blood from someone.
Beaker A: 50u Fluorosurfactant, 50u Space Drugs.
Beaker B: 50u Water, 50u Blood.
