Read what the parents say…

“Extremely good value for money…we found it easy to put time aside to do an experiment every couple of days”

“I cannot recommend this subscription box enough. This isn’t only because of the actual product and the fun we have encountered, but also because of the people behind the product. The customer service we have experienced has been second to none,” 

Lorraine (It’s a Family Adventure)

“This box was aimed perfectly at Miss A’s age range. She was completely engrossed in the experiments throughout and can not wait for the next box to arrive! … “

“The box is great value for money…the quality and presentation excellent…build up your own Science kit.”  

Patricia (Four Little Girls… The Mummy Memoirs)

“The attention to detail is amazing and it has been put together in a very visually engaging way.”

“The first box contained a well designed instruction sheet and all of the equipment needed to do the experiments. And I mean everything!”

Alan (Here Come the Hoopers)

“he gave it a “two thumbs up” which is generally reserved for pizza and chocolate treats!”
