## Questions & Answers

**Q: How big do the water beads get?**
A: The water beads are the size of any average orbee. Although some beads didn't 'puff' up all the way, they looked like raisins.

**Q: How many water beads does it come with? ?**
A: A lot. Do not put all the bag into the water at the same time!
I added the entire bag because the bag did not look that large and the beads were super small! We ended up having to put them in the bathtub.
I would suggest using no more than1/5 of the bag started. The more water you add, the bigger the beads get. Save the remained for replacement when the beads need to replace. I will buy this set of toys again for other kids. My kids like it.
