Why does Mister Mxyzptlk need to have a weakness in the comics? For viscous liquids, the liquid inside the droplet hardly moved around at all, whereas a fast mixing motion was detected in the lower viscosity droplets. The three -OH groups in glycerol are polarised and this helps them to easily dissolve in water. It is a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic.
