Now you can try your favourite experiment from the Explore Box and Investigate Box series all over again. Build your own refill kit by adding as many substances as you need to the basket. £2 P&P applies.

Please note that this is a refill kit, not a complete science kit, and does not come with instructions or equipment. Subscribers who have lost their instruction booklets can access them via their online resources.

Description

How does it work?

Each refill kit ordered costs £2 p&p plus whatever you choose to put inside – so you can order all the replacement chemicals at once to save on shipping, or just dabble with repeating experiments as and when you want to.

Subscribers that would like their refills to be included in their next box instead of posted separately can use the code REFILLMYBOX at checkout to get the P&P cost removed.

None of the refill kits contain harmful chemicals so no safety equipment is required to handle them. Safety gloves are included with the sodium alginate and calcium lactate in case of sensitive skin/squeamishness.
