A whole lot of people wanted to play with science over Christmas so our Investigate Box has gone out of stock. We are working hard to get more boxes ready and will be back in stock soon. If you would like to subscribe to the Investigate Box please enter your email address below and we'll reserve you a box and let you know once we are back in stock.

Happy experimenting.
