More Than Just Marbles

Yesterday the Flumlet told me, over the phone, that he was 'running marbles down the track' and I could only imagine the glass marbles being pushed along his wooden railway track, but that didn't sound interesting or enough fun to be reported to Nana.

Here is the track to which he referred, which he is loading the (plastic) marbles in the reservoirs, ready to be released down a convoluted system to trays at the bottom. Now, that is fun.
