Knitting Needles, A Sheet of Paper and a Water-Filled Syringe Make an Interesting Science Experiment

Astronaut Don Pettit, who, in a blog for NASA, conducts a number of different experiments in microgravity, once had the idea to demonstrate how water droplets behave in space. So he decided to pack appropriately, bringing 3 different knitting needles with him on the ISS. What happens is really quite amazing. You must see for yourself.

WATCH: “Zero Gravity – Water Droplets Orbit Knitting Needle”

 

The three different knitting needles are made of nylon, teflon and polyethylene. The image is of the teflon needle, after it has been rubbed with a piece of paper to give it a negative charge. The droplets are squeezed out of a syringe, losing their electrons along the way and acquiring a positive charge. The resulting combination of microgravity and electric charge cause most droplets to freely be tugged around the knitting needle, like clear and tiny planets.
