... i fell into a thorny bush today in front of a class of year 9's!!! We had taken them outside to show them a chemical reaction between bicarb and vinegar when they got a tad silly and dropped their pots of stuff. They had the reactants in a film pot with the lid on and were supposed to put it on the floor and watch the lid pop off. I stepped backwards to avoid getting covered and someone put a pot right in front of me.I turned to avoid being splattered again and ende up going head first into a bush of thorns. My arms and legs are covered in cuts and scratches. I went for mt flu jab earlier and found out my tetanus is a year out of date so it's been nice knowing you all!!!!
