So I have a stock solution which is what I have made using the instructions in The Laboratory (also previously mentioned) and I have one or two working solution bottles. I carefully pour the liquid from the st...

Haven't received an envelope here.................................yet!

For food....
we did periodic table cupcakes one year......pretty tedious

Mine don't even have rubber ends, just glass!!

Thanks Elizabeth,

I've printed that off and will give it to my teacher.

Thanks everyone!
