My 7 year old twins had a BLAST! So much to do and so many great demonstrations. We saw a meteor form in a mans gloved hand! We saw a laser light show explaining the different spectrums of light. We also made and raced Mars rovers out of Legos. We actually ran out of time and missed out on 2 other demonstrations. We had a great time and really enjoyed the trip but should have planned for a longer trip. 2 and a half hours just wasn't enough!
