When I was in college we had to do burn outs at assigned time and had to
wait for days some times so we put our flasks with the set up
investments and ready for burnout into a coffee can with a trivet on the
bottom with a little water in the bottom to keep the moist ness in the
investment so it would not dry out completely, on the other hand I have
a friend that lets them set for days sometimes and all seems to work out
that way to. I like the moist way because that instructor never sent me
down a wrong road and to him it was very important to do the water.
…on the other hand, if we let an invested flask sit for more than 24
hours, we run the risk of streaking and blurring…depends on how humid
your area is, we surmise.
