This is what my daughter asked me when I told her that this little cart most likely held an overhead projector. I didn't even have the luxury of having an overhead my first years teaching and now kids don't even know what they are because they are so old.
Sigh...But the new technology means these little carts are obsolete. When I spied one at the thrift store I knew it would be perfect for a side table.
Some paint (I used Chalk Paint as my first coat--the red so thr paint adhered well to the metal.)
and a barnwood top secured with screws from the underside
transformed this out of date school fixture
into a fun rolling table. A bonus is the height can be adjusted.
