We've been going there for years and this time they had a group of teens volunteers that had poor supervision. They were using the stuff for themselves while the place was full of smaller children waiting to use them. They did not help at all, others stucked on their phones and playing rough with each other with all the visitors kids around and they did not care. A person ( supervisor) came in once to put order and as soon as she walked out it all started again...very unusual and very uncomfortable. It may be a program, but if is so, is not working. This place is supposed to have a different dynamic where the visitors can enjoy the exhibits, sharing and having fun. This teens were double the size than the visitors and did anything to help or participate with them in the different parts of the exhibit, on the contrary they played very rough with each other, ignoring where they were. Very dissatisfied and clueless about why they were there. I hope we don't have to deal with this situation again
