I already had a set of the sinking sticks that have number values on the end, but adding four from this set makes it really fun when there's a group of people who have to dive for them. The winner isn't necessarily the one who gets the most sticks but the one who collects the most points.
We like all the toys. Some float rather than completely sink, but that just makes it more interesting when you're trying to find them. The blue ones are especially hard to find since the pool liner is also blue.
They're super fun to play with, and I'm super happy with my purchase!
