Showing a burning splinter and watching it burn well?Well that's how my teacher always says it so i say the same way.You just put a flame over the testtube and see what happens.As Oxygen supports burning it will burn very well.Sort of like a turbocharged flame

Which I guess is sort of what you suggested about oxygen supporting the burning and you did mention the splint which is what I was looking for. So...Answer: Place a glowing spling into the test-tube and it should relightWell Done AG. That's 1 point. Any newcomers are welcome to join.
