Van De Graaff Generator in British Sign Language (BSL)

The sign for “Van de Graaff generator” is used when discussing this important piece of scientific equipment, commonly seen in educational settings, especially in physics or science demonstrations.

How to Sign “Van De Graaff Generator”

1. Start with both hands in a flat ‘B’ handshape (fingers extended, palm facing down).
2. Position your hands together in front of your body, about shoulder-width apart.
