DOESUM software + support

This was the second time I've taken my grandkids here. While they really enjoy some of the activities, the ones you'd expect to be the main attractions were either too difficult to perform (kids don't take time to read all the instructions given) or the devices were not working or had parts missing like the Animation Station, Plot a Storyboard --- pens missing or died up markers; Robots not working; no materials for building the Wind Machines. The outdoor activities were great, but you can find these at most city parks for free! I won't be back.
