Triops...will they work?

Since Aaron loves little creatures so much, Alan and Kate sent over a science experiment kit where you can grow little sea animals called “Triopses”. They are supposedly from the Jurassic age. We had to go to Bluehill to get spring water (it’s literally available on tap, for free, at Bluehill) because they can’t hatch in chlorine water. I’ve followed all the instructions so we wait to see what happens with them.
