Electric Rainbow Jelly



Happy Tuesday.

Has anyone here tried to make the electric rainbow jelly in Neil Downie's book Vacuum Bazookas, Electric Rainbow Jelly and 27 other Saturday science projects?

I am trying to make it and his directions are not too clear. He says to make a strong gelatin solution...what is a strong gelatin solution?
How much universal indicator am I supposed to boil up with how much water?

So if you have done this I would appreciate any help

Thanks
Tina
