I saw this item in Wired Magazine's holiday gift guide of "100 Best Gifts for Geeks." It brought back memories from my own childhood having an ant farm. with it, the colony's disastrous and premature end when a family member accidentally knocked it over. Such advancements in ant-farm toy technology renewed my excitement, but it was too late to add to my own list so I ordered it for myself and it arrived the first shipping day after Christmas. The instructions are clearly intended for children and no adult-version, so the directions give some suggestions and ideas but left quite a bit open--not a bad thing, and I *will* say they do far more to inspire curiosity and encourage creativity than my old ant farm did.
There were a few things I have even already learned myself, however a few of them would have been nice to know when *assembling* the pods. Most of it has to do with how the ants behave and adapt to the pods, not so much the fault of the Wild Science Ant-O-Sphere kit... however it would have still been nice of them to include in the "TIPS" section.
Being winter in Wisconsin, ants are also in rare supply so I actually bought ants online. Western Harvester ants are actually quite cheap and easy to order online, as they are food for the horned lizard, and ordered 50 ants for $6.95 (shipped) from antsalive.com. (Make sure you read my notes at the bottom if you decide to go this route). They have had been in the ant-o-spheres for about three days, at this moment. I'll update if anything else comes up.
First of all, it seems that harvester ants are not great climbers. This makes empty pods a problem, and it is disheartening watching an ant fall down into the bottom, begin to climb the side, slip and fall back down to the bottom, only to be doing the same thing when you come back an hour later. Some layout redesigns were in order, seeing as the booklet suggests leaving several of the pods *EMPTY* from the start, and I feared that most of my ants were going to perish stuck at the bottoms of these spheres. The packaging only included enough sand to fill one pod (and by "fill" I mean I mean filling the lower half), so it may not hurt to buy or find some extra sand beforehand... however my ants seem to really be taking a liking to the soil filled pods more than the sand.
IMPORTANT ADVICE: Start by introducing the ants to only maybe 2-3 interconnected pods at a time so you (your child) can make sure that your (their) ants are adapting and reacting to your (their) pods as hoped, and then add on by connecting one or two more pods instead. While the post-modern styling is visually attractive, it is not advantageous when you have to take a pod apart or want to change anything. I had to disconnect and remove the top four pods and swapped the empty single 2nd-tier pod with another soil-filled one once I saw how poorly the Harvester ants did climbing up smooth plastic walls.
RE: Ordering ants online
I looked at a number of other websites but they all appear to be the same (western harvester ants) and priced similarly. I went with antsalive.com because some other places don't ship to certain areas during winter and because shipping was free. They arrived a few days ago, and while I expected a few dead, it appeared nearly all of them were alive. If you follow this route, do be aware that harvester ants DO bite... so this part is clearly for the adults. I had tamped the tubes a couple times down on the table, to get as many away from the top as possible, then quickly opened both tubes, turned them upside down into the collection jar and tapped the sides to coax them out. I had the lid--with hole pre-stuffed with a cotton wad--ready nearby; this part probably wasn't that important due to their limited climbing ability. This technique worked moderately well, however it seemed the ants were *very* partial to staying in the collector jar and it took a long time for them to make their ways into the pods---there are still 5 (living) ants that still will not leave the collector jar.
There was a single stubborn ant who had stayed in one of the tubes and instead of worrying about him while I had the rest in the collector jar I just put the top back on the tube. Later, I checked to see if the top of the vials fit nicely over the plugs of the pods--which they will, loosely, if held on--and released the single ant to another plug through this method. Given the confined space of the vials, he didn't take long to take it and escape to freedom. I think I may attempt this somewhat riskier technique in hopes of quicker results. Additionally, emptying them into one of the smaller "food/water" jars would also probably have worked better, the smaller size leading to much faster discovery of the porthole.
