I ordered this product for my kindergarten class it based on reviews found here and there on the internet but with out a doubt still on the success of this project ... and I must say that I was blown away! On 10 caterpillars at first (we ordered a lot more tracks), 10 butterflies in! In just over 3 weeks, with poor weather conditions and without any constraint (no need to feed the caterpillars they already have what they need in their pot), it's perfect for teachers who are not necessarily very gifted with the little beasts! ;) The children were fascinated to see every day the caterpillars grow visibly then discover cocoons and finally see live butterflies out. Frankly I am delighted with this product, the explanation leaflet is very well done and I would not hesitate to recommend it to all my colleagues for a project on the living. Just to clarify: once hatched butterflies, we did not saving more than a day in the greenhouse, this is why we have had 10 butterflies instead of the 5 recommended for a greenhouse of this size.
