I was given this as a leaving present, as a kind of joke, but my colleagues didn't realise I've always loved ants and really wanted one of these for ages! I wasn't disappointed. This is a well-designed product which provides hours of entertainment and fascination. I've seen all sorts of strange things going on in my Ant World: ants moving things around then back again like women designing a living room with furniture, a brutal murder when an ant I thought had escaped turned out to clearly be from outside (i.e. it was killed within minutes of entry), and interesting preferences for lunch: fruits not as popular as one might think, honey, other insects and even nuts proving popular on the menu. Further, there's plenty of ways to improvise with this kit, and I also think the teamwork ethic the ants display is a nice lesson for children (and adults!) I've had this product for 3 years and bought another one to compare red and black ants. The reds I brought in from outside, the blacks I ordered from Interplay. Enjoy!
