This had to be number one on this list. It’s by far the most successful invention that has come out of Shark Tank. It started off as a sponge to be used to clean one’s hands and exfoliate them. Now, it’s grown to sponges and wands of all kinds. They’ve become so successful with their products that they have raised $18 million and have their products in major stores such as Wal-Mart. Shows that even with age old products like sponges, there’s always room for improvement if someone has the right mind.
