Re: HELP!!!! Presentation
55 minutes, that's a while to keep people interested. Some kind of humor is always a good option.

Re: HELP!!!! Presentation
What about volcanoes. We do a great volcano demo. Soln1 3 teaspoons Aluminium sulfate in 100mL water. Add some food colouring.
Soln2 3 teaspoons Bicarb in 60mL warm water. Add 2 teaspoons gelatine, add 40ml extra water and stir.
Put a conical flask in a tray. Pour solution1 into the flask.
Quickly but carefully pour in soln 2.
Flame tests go down well. Everyone loves a bunsen.
Good luck, Ellice.

Re: HELP!!!! Presentation
The bicarb reacts with the acidic Aluminium sulphate producing froth. The gelatine provides substance to the froth which rises reminiscent to elephant toothpaste
