You know from planet of the apes, how they made the cast members put on those dots? I was wondering where I could get those for something I am making. No dumb answers. Bye.
It can be stored indefinitely , just make sure that you DO NOT pour water into the concentrated acid . Always pour acid into water to make solutions . Keep the acid in a well ventilated storage closet keep it tightly covered so that no water can get poured into the container as it will get VERY HOT VERY QUICKLY ! Always use rubber gloves and wear goggles and a protective apron when working with chemicals !
yes all pvc pipes and fittings and valves are air tight
