Paul's suggestion was along the lines of what I was thinking - less mess than water or dye, and still addressing all the combined requests for experiments showing buoyancy (or lack thereof) in zero g.

One way to show this would be to attach an acrylic (or other clear) container with the He balloon inside to an RC car on a curved section of track. In zero g, any motion of the car along the track should cause the balloon to move towards the inside of the radius of curvature. If you also had a ping pong ball inside the container, you could show the two objects move in opposite directions.

I don't think I've ever seen video of anyone playing with helium-filled balloons in zero g.
