I went there in 2019 and I didn't see the bed of nails did they get rid of it?

A bed of nails is at WonderWorks.

The complete bed of nails display is no longer at the Gatlinburg TN location. I went last weekend also, and they've got a couple of new displays that have replaced a couple of the previous ones.

I wen last week and it was still there in a corner

I just went last week and didn't see it either.
