An article (here) about a recently discovered First Temple-period seal noted:
- From the very start of the excavations in this area the archaeologists decided that all of the soil removed from there would be meticulously sifted (including wet-sifting and thorough sorting of the material remnants left in the sieve). This scientific measure is being done in cooperation with thousands of pupils in the Tzurim Valley National Park. It was during the sieving process that the tiny seal was discovered.
There are just some experiences that even the best day school education in galus can't replicate.
