What was hard or easy.? It was easy to make the worms

Have you ever wondered what makes a polymer? A polymer is more than one monomer. First put one teaspoon of calcium chloride with water then suck up some of sodium alginate [from seaweed} with a pipette. Squeeze the sodium alginate into the bowl with the calcium chloride. Then you can squeeze and hold thne pipette to make a gummy worm. This is an irreversible chnage.
