One of the few advantages of the downturn in the US economy is the favourable exchange rate. The most impressive Science Shop I have come across is teachersource.com from the good ol’ U S of A.

I must have paid the guts of €40 for the Hyman Fire Piston from TechnologySupplies.co.uk from England, which admittedlyis also a very useful site.

Teacher Source has it here for $18.95. Maybe €12 or so?

They are also amazingly prompt. I used them quite a few times and delivery is usually within ten days, sometimes even within the week. I did get caught with Customs Tax once though.

Loads ‘n loads of cool toys educational resources!
