There are miniaturisation beams, microrobots, and ice skaters who suddenly drop into a hole in the ice. Students of the local MBO Rijnland let their imagination run free while animating Leiden physics research. The result is eleven surprising and very diverse science animations.

Ionic liquids are important in scientific research because they can apply a lot of charge over a surface. Leiden physicists have now found that the charging process of ionic liquids purely depends on opposite charges attracting each other. Chemical reactions are sometimes involved, but not essential.…
