We took our kids here (14, 7, & 5). They all loved it! Going to watch them hand blow the glass is completely free. However you may spend some money in the little gift shop after you watch the glass making experience. Prices vary. The man that volunteers, evidently he does this weekly & loves it, he was very informative and was able to answer a lot of questions and explain the process so even the young kids understand. It's definitely worth seeing! Especially if you're at Jamestown b/c it's pretty much right around the corner, but you do have to drive there. Parking is free.
