Ideas of questionable quality

Flour chem! Use the chef's flour on a beaker or shove wheat into a reagent extractor to get a chem that makes people cough and drop their items.
Cornstarch! Shove corn in a reagent extractor for this, which can be used as a condiment, a precursor to very high fructose corn syrup, or mixed with water and heated to make...
Oobleck! Fun to play with, but pour enough of it on a jumpsuit, outer suit, or helmet, and it makes it bullet-resistant. Bullets do less damage when faced with oobleck, but do slightly more stamina damage. The same is true for blunt objects.

Iirc corn starch actually exists already and it is used for corn syrup
I would love to see obleck though
