And one of the issues here is, you can't just go and get the materials from the beach, because if you get a bunch of mussels and try to milk them for their adhesive, you'll get a little bit of material, but you're never going to have enough to do anything with, just enough to see.
Y uno de los problemas es que no pueden simplemente ir y tomar materiales de la playa porque tomarán un grupo de mejillones y si tratan de extraerles el adhesivo solo obtendrán un poquito de material, pero nunca lo suficiente para hacer algo que sirva, solo para ver.
