[IAEP] Sugarized Sound Speed

[Dominik Granada]

Hi, 

did anyone try to repeat Ch. Stoll sound wave measurement http://www.ted.com/talks/lang/en/clifford_stoll_on_everything.html (starts around 10.30) on Sugar/Measure Activity?

I could not introduce second beam - all sounds merged in one. Any hints / ideas?

Thanks
DG
