I just read this story...
Yes... waterbeds - for dairy cows!
Apparently, it improves the quality of the milk!
This would have been a good product to have invented (and patented)... I'm sure the inventors are now "cleaning up" (and will profit for years to come)! They've apparently sold half a million cow waterbeds already...
I'm posting this for inspiration...!
Waterbeds already existed - they just had to be adapted for use by a 1,600 pound beast.
