Bests & Worsts Reviews from Amazon

This is a really good kit, but beware of the hidden costs! The price of the kit does NOT include caterpillars. If you buy the kit, they give you a code to purchase caterpillars for free, but you still get charged about $5 for shipping and handling, plus more if you want the caterpillars expedited with 2 day shipping, which they recommend so that your caterpillars don't die in transit. I chose not to pay more and chose regular shipping, and my caterpillars arrived within 3 days in excellent condition. If you want another batch of caterpillars you have to pay about $15 for the caterpillars plus shipping. So buyer beware! But in spite of that, this is a GREAT little science kit. My 4 year old son was fascinated by the caterpillars that arrived. They come sealed in a little plastic tub with a layer of food on the bottom, so you don't have to feed them or tend to them at all, just make sure they are neither too hot nor cold, and watch them grow! They eat the food on the bottom and hang on the top and turn into chrysalises. About a week later they turn into butterflies, and then you can feed them fruit or sugar water, which is a lot of fun too. We received 6 caterpillars and all 6 of them turned into butterflies. So beautiful and really great learning for the little ones (and us big ones too). A note: Make sure you are going to be home for at least 3 weeks when you order the butterflies. If you go out of town you might miss the transformation, and also once they turn into butterflies you need to be home to feed them.
