Screaming Jelly baby - alternative to Potassium Chlorate?

Discussion in 'Science' started by choccie, Feb 24, 2009.

  1. We do screaming jelly babys at school and successfully in the fume cupboard you just use half the amount of kclo3, It still gives an impressive result but the fume cupboards cope better with the reduced smoke produced and you can do twice the amount of jelly babies.
     
  2. Sodium Chlorate has the wrong melting point

    potassium much better salt to use, lilac timge to flame.

    Any body comment on the final burst of white light at the end of combustion.

    I have seen this done with roundtrees fruit pastilles as well. Each coloured pastille gave a different colour to the flame.

    I have also heard but never tried. Apparently if you cut a split up the middle of the jelly baby (like separate his legs) then he screams louder!

    Bite his legs off first - stops him jumping out! (that's what I tell my students...)
