Re: [DIYbio] Re: help out a noob, marmite for malt medium?

Warning: if using a butane bunsen (campinggaz style) do not invert the
bunsen! :)

Get a culinary blowtorch for this instead, or better yet learn to avoid
making bubbles in agar in the first place; swirl, don't shake, and let
it cool a bit before pouring. Bubbles burst on their own in hot agar,
but once they form in cooling agar you're in trouble.

Another nice trick; swirling a poured plate gently will encourage the
bubbles to the edge of the agar plate, where they can be either ignored
or encouraged together with a sterile needle and popped.
