This drop of metal is not going to morph into Robert Patrick (we hope), but it could be a breakthrough idea in how drugs are delivered into the blood stream, according to Discovery News.
Scientists from Tsinghua University in China mixed together gallium, indium and tin to create the liquid metal. They then attached a small amount of aluminum to the drop. When the drop was introduced into a container of sodium hydroxide (or just plain salt water), a chemical reaction occurred. Tiny bubbles created by the aluminum and the solution propelled the drop due to an imbalance of electric charges between the drop's back and front, according to Discovery News.
Remember when we said the drop won't morph into Robert Patrick? Well, the drop does morph... sort of. As the drop traveled through the predestined path, the drop adjusted its shape and size when necessary to squeeze through tight spaces.
