Sensor of pee stream Position?

Position?

Hi,

I'm working on a project at school and I need suggestions on sensors... I need to track the exact position of someones pee..

I've tried to make an "multi-touch" useing a webcam, paper and glass.. But that didn't track the pee at all... I've also tried to make my own presure sensitive sensor but that also failed... Now I want to buy a sensor, but I really don't know what I'd buy.

I found a sensor, but I'm not sure about it:

It's a temperature sensor.

Thanks in advance,

These guys were using piezo sensors for a similar purpose: **broken link removed**
