What do I do on a hot saturday afternoon - try and catch ants with my 2 & 4 year olds. Bought the blue gel Antquarium from Argos a while back (saw it here in the deals section) and now I'm really beginning to wish I hadn't bothered!! Anyone else get one? Once you've caught the 1st one you think 'hey, this is easy enough'. But after that it all goes down hill. The reason is you have to take the lid off to get the ants in and so the ones you have got all escape!! I've got 4 alive ones so far (need 12-20) and 3 squashed ones, which don't count and I've been doing it all afternoon! ou're supposed to change the ants after 14 days fo new ones - I can't see that happening!
