A lot of vintage junior high school science equipment.

These items are from an old sealed science lab in a junior high/high school in Brooklyn NY next to McCarren park.

A great selection of oddities for sure.  Please see the photos for what you get and the condition.

The Kaleidoscope works.  The clock winds but I don't know how it works beyond that.

There are some cool little vintage containers - great accent pieces.  

The reciept holder (spikey thing) might be from the 1940s or earlier.

A real gem is the box of slides.  They seem to be of architectural interest, old homes and such.

The books are dated from 1963, and were all together with the other things so the range is 1960s and before.

(The Sharp clock might be 1980s.)  The old wooden block with holes is probably for test tubes.

I priced out about half the items on ebay and it looks like all the items together might be worth northwards of $120 or so.

Good luck!
