    Fun exercise to demonstrate bernoullis principle that I love to whip out. Take two pieces of paper and hold them from the top so that they’re hanging parallel to each other. Blow air between them. Most people expect them to go apart due to the air coming at them, but the higher velocity causing lower pressure means the static air on the outside of the papers actually pushes them together.

    I went to a science center that had a demonstration with two heavy stone balls and an air cannon. The cannon was powerful enough that the balls actually touched. Mind blowing.

    I try to give paper wasps a pass if I randomly see them, but if they come inside or start a nest in outdoor equipment, they’re gone. They only get consideration because they’re pollinators and generally not aggressive, but they still will attack so my patience is thin.

    To them you are a giant who can easily kill them

    And I relish in proving them right. Fuck wasps and fuck your wasp propaganda.

    I’ve given bees snacks when they’re tuckered out on a hot day. I’ve let them rest on me. But with wasps and hornets it’s on sight.
