"File:" cannot be used as a page name in this wiki.

[edit] Shopping

Everything bought should have a bill with your name and the mention SciFe so that it can go to the correct budget.

Here is the shopping list established last meeting:

  • 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 is open until 19:00
    • 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)
    • water hose

[edit] Still no source how to get big amount of corn starch!!!

provencale: who can go there?

[edit] Need list of people who will be at the actual festival

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)


  • water pump: just use an aquarium pump or fountain pump
  • soap pump: probably print it <= this did not work well!
  • 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
