Test tube caps, do they burn you up also?

[fish_4_all]

A had to start this because 7Enigma made a really good point. I always lose liquid out of my test tubes. It is really annoying and I would agree, is potentially dangerous.

What do you do to keep the liquid from leaking or flying out?

i dont seem to lose any i dont shake them upside down for that reason just up and down

It's not necessary of frantically "shake" the test tube. Just turn it over slowly, and then turn it over again. Doing that a couple times is enough. The liquid can't "fly" out then (although if your cap doesn't fit tight enough, you may get a drop or two dripping down the side). If it still leaks, I might try "investing" in a smal rubber stopper (like the ones in chemistry class) from American Science and Surplus or other science suply store.
