I just bought this Live Butterfly Garden marked down to ONLY $11.99 (no longer on sale) for my kids! They're 3 (almost) and 4 1/2. This kit comes with a relatively easy-to-assemble observation chamber; supplies for feeding the butterflies (you provide only sugar and water); an informative booklet of clear instructions and butterfly facts; and a certificate for three to five free painted lady caterpillars! Your kiddos will actually be able to watch the metamorphosis from larva to butterfly which takes about three weeks. They can then release the butterflies after a few days of observation! Perfect time for Spring. Easy science activity! It currently has 297 reviews with 217 of them 5 *'s.
