Home movies from Summer of 1961 show our kids enjoying the Slip and Slide. I don't know exactly when it came out but it was long before the 70's. I thought you might want to know about this correction but I couldn't get the correction form to go through. Slip n Slide]] This was a very long strip of yellow type of plastic which you put on the grass, attached to the hose, and ran and slid on. There was also that crazy attachment that went on the hose, and when the water was on full blast, it would fly all around, shooting water everywhere.
