That reminds me of how the chemistry teacher at school caught me out. He asked me to put a lighted spelter to a small plastic bottle in which he had collected hydrogen. I was cautious and I think the bang was greater when I finally lit it as the contents had had time to mix with more oxygen for a more explosive mixture
