That is cool. Dust? What's that? Ha. Ha....oh, I know what dust is. Utah ..there is dust. Dust comes into our house. We can't keep up. I try.My adult son put together a Lego space ship (think that's what it was called). It ended up over 5 ft. long- he had/has it on his dining room table.
That's the problem with legos, what to do when you finish them? I once bought a 6 ft.table and it held a whole town of shops and stores and had a train etc.(mono rail).Wow, but, after a while gets dusty - then what?

Hopefully they are negative! Sorry to hear that. Stressful.
