- Mix up some oobleck using cornstarch(we used cornflour) and water
Most recipes I found say 1.5 parts corn-starch to 1 part water but we ended up adjusting the mixture to suit as we went. The ingredients are so simple you can play with it.
- Pour it into a tray
- Slap the tray on a sub-woofer/speaker
- Ramp up the bass.
I went for 1/1000th of a second in the end which seemed to suitably nullify any motion blur, this ofcourse required some carefully controlled flash. Too much light will easily over expose the already white liquid and/or plunge the shapes into heavy shadows while too little light can result in a total lack of definition in the fluid or of course under-exposure. Shooting at a high speed such as this though does have the advantage that you can hand-hold the shot quite easily.
Really these photos exhibit a technique of what's called "high-key" photography. (Something I've previously been quite poor at in my opinion.)
Shooting a white subject on a white background is basically a challenge, any definition in the subject can only be obtained from well-considered lighting.
I think I've managed to achieve the effect I was after, if I was to do this again(which is likely) I would probably try to incorporate more colour, either using food dye or possibly some coloured filters on a couple of flashes.
Only question now is what to do next.
