And so you see here some early studies of blocks, where those holes are actually coming through, and this is before the thermo-bimetal is applied, and this is after the bimetal is applied. Sorry, it's a little hard to see, but on the surfaces, you can see these red arrows.
Ovdje vidite neka rana proučavanja blokova, kroz koje rupe zapravo prolaze u cijelosti, i ovo je prije nego se primijeni termo-bimetal, a ovo je nakon njegove primjene. Ispričavam se, malo je teško primijetiti, ali na površini možete vidjeti ove crvene strelice.
