The Hot Pepper

good luck. i think the nozzles are supposed to be some sort of cured bentonite clay right?

I think in theory, but one of the rules is things on hand or common. Each new try has to have some improvement.

kitty litter is like... mostly bentonite and some kaolinite and filler scented crap and some glue to make it granular. the bentonite is why folks use it to adsorb chemicals for safe disposal.

you might try crushing it into a flowable powder and forming a plug in the bottom of your rocket body... then drilling it out when it cures hard. thats what i would do anyway.

bentonite is super common. its in everything. its a simple alumina silicon clay (alumino silicate)

Funny cause we used kitty litter to make a clay for the nozle. Fuel not burning fast enough, going to find some iron oxide and try again.
