Fume Cupboards – Screaming Jelly Baby
A short video clip kindly supplied by AES, Glasgow showing the potential detrimental effect on containment during “The Screaming Jelly Baby” experiment!
This experiment is carried out as part of the school curriculum. It’s called the “Screaming Jelly Baby” experiment where a jelly baby is oxidised using molten potassium chlorate. The rate of expansion of gas quickly overcomes the volume flowrate (typically about 450m3/h).and face velocity (typically about 0.4m/s) of the fume cupboard.
