Tin foil caterpillars on cardboard, wired to a Makey Makey behind it. Touch one and it plays.
A child touches a strip of foil stuck to the front of the cardboard and completes a circuit. The board reads it, the computer plays the note.
It runs inside another activity rather than as a station of its own. At Meath Gardens it is the sound element of the sensory wall. It is held here because it has its own kit, its own power requirement and its own safety case, and none of those belong to cardboard.
Muireann owns it, and was testing it on 3 August 2026.
Quantities are in materials.csv beside this record. The
group column there is what an event's packing list is built from.
| Hazard | Who it reaches | What we do |
|---|---|---|
| Mains electricity | Everyone in the room | Socket, lead, board and computer behind the wall, out of reach. An adult with them whenever the activity is running. |
| Trailing extension lead | Everyone, including under-5s at floor level | Against a wall, taped down along its length. Never across a doorway or a tunnel entry. |
| Leads and alligator clips as small parts | Under-5s | Behind the wall with the board. Never on the activity table. |
| Conductive dough, eaten | Under-5s | It conducts because it is heavily salted, and it looks like something to eat. An adult stays at it whenever it is out. |
