South Carolina State Museum

Steve’s take

The state museum in Columbia has a planetarium, a 4D theater, and an observatory — which is a lot of firepower for a place most people drive right past on I-77. If you're stopping in Columbia anyway, this is a solid two-hour stop that counts as educational. The building is a former textile mill, which is interesting in that 'I'll tell the kids about it and they won't care' kind of way. The 4D theater, though — they'll care about that.
