1. daddy had a work meeting today. so we took some vinegar, bicarb and various pop top tubs to the park. we did an experiment to see what tubs acted better as rockets, L. told me why he thought some worked better than others. a couple of older ladies were watching us..
2. my 6 yo went over to them (respectfully and keeping distance) and asked them if they would like to see our science experiment. they (quite excited) said yes please. so he told them the ingredients and that when we mix them its an acid base reaction.
3. this produces gases which get squeezed up until the pressure is too much and it goes pop! the ladies were impressed with his little lesson and told him that that's what they use to help clean their drains but they had no idea it worked like that.
