Terry performs experiment with oxide of thulium at Harrogate lab
Oat seeds (wild or semi-wild) move in response to changes in humidity, and directional backward-pointing hairs make the seeds creep always forwards until they hit an obstacle. The attached photo shows about 100 seeds that were placed at random in a plastic tray about 2 months ago and left (under cover) outside so that they were exposed to diurnal changes in humidity. Most of the seeds have migrated to the outer wall and organised themselves into neat rows. Order from chaos!

Small Tesla coil created electric field which lights lamp
Chladni figures created by vibrating fine sand particles. The sand patterns are unique to the metal plate and the frequency. They change in a fascinating way as the frequency is altered, as the sand accumulates where the plate is not moving (node). Particles are shaken off where the plate is vibrating violently (anti-node)
