You can do this by 1) sticking the hot loop in the agar at the edge of the agar away from the bacteria, or 2) just holding the loop for a few seconds while it cools. Why streak from the bottom of the agar slant medium up to the top in a straight line, rather than a back and forth wavy inoculation from side-to-side on the slant?
