ok.. so a long time ago we tried the you-tube mentos stuff and happily wasted time (and coke) in the office parking lot.. (of course this was after half assed attempts to mimic the experiments imperfectly.. given the typical office makeup, this ensured that we tried it with various other softdrinks, various other sweets and at one point even tried microwaving the drink cause roelof thought “the cold was ruining it”.)
