This was great fun and I think the other hackers liked seeing some sculpture being made beside all the electronics hacking.

Compare that to the tolerable upper level of vitamin A intake for a healthy adult human: 10,000 IU’  Onto hands Orangutans have really short thumbs not going past the knuckle. T...

Microscopic surface tension

Pouring a small drop of a softdrink onto the palm Viewed through the microscope, we can see small particles on the surface of the liquid. Similarly we can see the surface tension holding the liquid in a roughly hemi-spherical shape on the palm. For some reason the group decided to pour pepper into a palm and microscope it.
