Join PTMSC docent extrodinare, Moh O’Hanlon, and learn how to build your own plankton net. Using simple household materials, Moh will help you contruct a net that you can use to filter tiny plants and animals from the sea and look at them under a microscope, revealing the world in a drop of seawater.
