Whenever I see fresh, new grass - especially when I touch its softness - I flashback to this “toy” I had in the '60’s. No one in my family remembers it.
What I recall is that it was green plastic shaped like a castle. The walls were maybe 2 or 3 inches high, and there were taller towers. You put soil and grass seed in the large enclosed area (about 12" x 6" ?) then poured water into the towers. Voila! Soon grass would sprout.
Did it zip when it moved, bop when it stopped and whir when it stood still? I had one of those too. I never knew just what it was, and I guess I’ll never will.
I still have a head made out of clay (think of a clay flower pot, but in the shape of a man’s head) that was made in the 50s. Same principal as the Chia-pet, but marketed long before. You put grass seeds in the grooves around the guy’s head, added water, and the guy grew grass/hair.
