Mahogany slide with recess cut inot it to accept the circular brass chamber that contains 3 Silhouettes of witches flying on broomsticks, activated by water flowing from the bulb into the brass tank and sweeping the witches around in the resulting flow, 17cm x 11cm. Note: acording to the vendor 'The witches dance defying the force of gravity, as the audience is totally mystified by the magical effect as this slide is projected. As well as the witches jumping, they appear to be having fun and playing games as bubbles appear from the top defying the laws of natural gravity. It is the only known example of this slide still in full working order. Prior to use, the brass tank is filled with water and small amount of liquid soap.'
