Look at 'em go!

A continuing report of our ants' progress in their strange gel world... They have finally started to tunnel! It's a fairly short tunnel so far, but they are small ants, so it's both a lot of work and a long enough space for them. In my last report, I said how they had dug a big hole in one corner of the box, but then they just spent a bunch of time huddled there. Now they have made two tunnels branching off from this cavern-like hole they dug. One tunnel is small and just curves back up to the surface, the other is the main tunnel that they've made towards the center of the box. O posted a photo of it. It's a bit hard to see the scale here, but it's only a little more than an inch long. Plenty of room for them all to fit down there and walk around a bit. To the right in the photo you can see the first part they dug, which is quite wide and circular. I guess it gives them a good area to rest or get out of the way from ant congestion in the tunnel. I also like the strange texture the tunnel wall has, which I guess is from them nibbling away bits of gel when digging. It looks like that pebbly glass that is used in bathroom doors so you can't see through. And they've made a complete mess of the surface of the gel. Pieces of gel are scattered all about. One to two ants still wander about on top all the time, and occasionally you see one pick up a clump of gel and move it to another spot, which might have made sense to the ant, but seems rather pointless to me.
