What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes. You can also expand on the activity and teach it as a one-hour to two-hour workshop. As extensions, the What Else? section suggests other activities related to food and music. This is a fun activity to do as a walk up for all ages. Note: This activity uses an older version of the Pico Cricket. Some revision may be necessary for later versions.
