We're trying to create a mechanical interactive for our exhibit about blood. We
want visitors to see an oversized vial of separated blood. Then they shake it
up, and then the vial appears to be filled with whole blood. Then it resets for
the next visitor.
Has anyone seen anything remotely similar to this? We've been imagining beads,
glycerin, colored light, paint shakers, snow globes, etc. but we can't make it
work. Any tips will be much appreciated.
