77 - Magnet

Theme 244.

Taken in the Launchpad section of the Science Museum, London on the last day of my long weekend there. There were lots of activities for kids, like wave machines, magnet coils, etc. This had metal cylinders you could stick iron discs to, magnetically.

I was being careful not to include kids in the photos - so I got this photo but didn't try for better ones, as I didn't want to be standing around too long as a single person with no kids, trying to take photos in a kid-centric area!
