Making things collide involves timing the trajectory of the elements in a shot, aiming of the trajectory and it’s timing and then adjusting these until the collision occurs. To do this we usually use Arduino or MAX MSP.
Beer and foam collide
A great example of making a collision is a CASIO test we made for the last Duvel commercial with Stef Viaene. By gradually adjusting the power of a pump and a magnetic release we were able to effect a collision of foam and beer.

Drops of milk colliding
One of the shots we worked on was making drops hit each other in mid-air. This drop mix is a compilation of very strange amorphous shapes created in mid-air.
Wave of wine
For the Boursin shoot with Bram Coppens we made a wave of wine “going over the top”.
