Hi Maree

I've attached a file with another polymer recipe. This makes the gooey slime that kids love. Initially the slime is quite wet and sticks to fingers, but it dries after a few hours - even less now that summer is finally here. Maybe try 20 mL less water and compare.

I don't know for sure, but I would say that if a permit is required, a record of usage is required too.

If the delivery tube is only used for experiments that don't involve heating e.g. CO2 into Ca(OH)2 produced from HCl + CaCO3, flexible straws are the way to go - especially with lower school students. Best type are Deeko Entertainers as they have a larger diameter than most. For smaller dia straws, ...

I copied the following information from the RTG website (for WA techs). This site is invaluable and well worth a look. The action of saliva on starch - another view. The standard procedure for this experiment is to react starch solution with saliva and then test for the production of sugar. As an al...

Cash & Carry (formerly FAL) Balcatta, WA, sell Anchor distilled (deionised)water for $6.43 (ex GST) per 15L cask. The cask is the same as those used for "Chateau Cardboard" wine. Advantages are that they're cheap, portable, greatly reduce wastage and are much harder for students to con...
