Did you know the CSIRO in Australia created some of the world's roundest and smoothest objects: ultra-precise silicon spheres for the International Avogadro Project. These spheres are so smooth that if you scaled them up to the size of the Earth, the highest ripple in their smoothness would be just 12–15 mm, with a roundness variation of only 3–5 metres. CSIRO master optician Achim Leistner, known for his extraordinary sense of touch called "atomic feeling," played a key role in achieving this precision

LOL. It was shredded lettuce in the 5# bags. Not bagged salad. I want the real stuff!
There's now 2 ozempics....

Uhh, is the relevance that these would be easy to drop?
very slippery indeed!
