whats worse.. last year we were doin an expriment in the chemistry lab and it required that we warm the test tubes in a water bath.. so the teacher got this electrical sort of machine with holes in it to put the test tubes in.. he filled the inside part with water and switched it on.. and told us that its ready for use. everyone put the test tubes in... but no reaction happened.
The teacher was like.. "the process may take time...."
we waited for like 30 minutes and nothing happened
then the teachers like "Oh silly me, i forgot to plug it in"
what a complete idiot!!
