Squeeze Machine Essex North Job 16/1501
This is the third Squeeze machine Essex North has made. They are all similar being two air mattresses constrained so that a person lying between them will be squeezed once they are inflated.
The pump for this incarnation is a modified Mangar Bath aid pump. The article in the School Newsletter explains the theory better than me.
