dampening the sand in front of the primitive device reduces friction on the sled, making it easier to operate.Let me see if I've got this straight? If the surface is wet, the coefficient of friction is reduced?? Wow, maybe that explains why I go into wild spins every time I drive in the rain! Maybe next time I'll try slowing down in the rain!
Who knew???

But missed the most important part.
The scientists said that the Egyptians had a "contraption."
Slicking the ground with water AND using a contraption is what did it.
