Part of the Cambridge Festival 2025
The Re-Volting workshop will feature three interactive, hands-on segments:
1. Building a Zn-Cu Battery:
In this first segment, participants will learn how to create a small zinc-copper (Zn-Cu) battery using everyday fruits and vegetables, such as lemons, and measure its electrical potential.
2. Coin Cell Assembly:
The second segment invites participants to assemble their own coin cell battery. Using materials like copper (Cu), zinc (Zn), a separator, an electrolyte, and coin cell components, they will fabricate a working battery.
3. Roll-to-Roll Manufacturing:
The final segment uses a pasta roller to demonstrate roll-to-roll manufacturing techniques, similar to those used in the battery industry. This segment is especially designed to engage young children and introduce them to industrial battery production methods in a fun, hands-on way.
Age group: 3-18
