We need to get going with seriouns planning, aquiring materials and making our experiments work for kids. This day will be in 2 groups * a group to create the experiments for the kids ** make corn starch ** play around with it ** drop stuff on it ** try to pour soap to create the kaye effect * a group to create the public event ** loudspeaker corn starch ** kaye effect setup (continuous running, with a pump) ** corn starch pool design ** cleaning station design (another pump) Hornbach is open until 19:00, we can go buy stuff the same day Ideas: * water pump: just use an aquarium pump * soap pump: probably print it, c.f. pumps used in hospitals * pool: wood planks covered with thick foil and on the top edges foam to isolate pipes * loudspeaker: there is a plexi tube available, it's not very wide, but it's free. Put speaker on bottom, corn starch can't escape. Coat the tube with lotus-effect cleaner. (need to aquire correct size speaker(s) for that) * big speakers: have several sets of stretched foil in a frame to quickly put on the speaker * creating big amounts of corn starch: get a drill with mixer and solid buckets Everything bought should have a bill with your name and the mention SciFe so that it can go to the correct budget. Shopping list * supermarket ** big transparent bowl (for kaye effect on curved surfaces) ** various soaps (hand dish washing) and shapoos to test for kaye effect ** other common household items (mayo, ketchup, caramel topping ...) showing non newtonian properties * hornbach ** cement buckets (to mix corn starch) ** drill (a normal power drill, with slow gear) ** mixing bit for the drill (kenn brought one, we need a second one) ** 3m*1m pool plastic (take 2 or twice the size, in case one breaks) ** 3x 2m*0.4m wood (for the sides and the floor of the pool) ** 2x 0.4m*0.4m wood (for the heads of the pool) ** 5m pipe isolation (for the top pool edge) ** tons of power tape (no we will not build the pool out of power tape like mythbusters) ** steel angles to fix the wooden planks ** screws ** aquarium water pump ** fountain bed (to avoid falling water from spashing)
