Build a fish, anyone? Fun website!

Here's a really fun site -- which enables you to learn about fish by allowing you to actually build your own, release it out into the ocean and see if it survives... or gets eaten by a shark (as you can see in the picture, I wasn't taking any chances!)

It's not, obviously, intended for young learners of English...

Why do I include it? Two reasons (1) I think it will amuse you and (2) I think the question "Would my kids actually learn any English from it if I took them to that site?" is an important one to consider when you come across things on the web...
