I totally agree with the authors point. The Franklin Institute at its core is a place that teaches science through tactile experience and the special exhibits don’t reflect that.

Some context as a local though, the Franklin Institute’s special exhibit space rotates every couple of months and I imagine they’re put on by outside vendors who move the exhibit from venue to venue. The special exhibits for better or for worse more akin to Disney World or the pop culture museum in Seattle. I’ve been to a bunch of them and they’re usually quite good, but they don’t represent that tactile learning experience at all.

Many of us Philadelphians really lament that the place isn’t as well maintained as it should be. It was the field trip destination for so many kids and I’m sorry OP wasn’t able to recreate that same level of magic for their kids.
