## 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.

### ⭐⭐⭐⭐ Review
*by N***N on 12 November 2021*

Very quick postage and quality product. Planets look exactly as pictured - they even have the name printed on them (but very small and sometimes obscured by the colour of the planet). I was a bit surprised to find the “Sun” written very small and a huge “made in China” on the other side. I had read a review or two saying the astronaught looked cheap, I did not find that the case. The astronaught are made of thick plastic and look durable and realistic and of a good size for small hands. The planets are sqishable foam balls. There are also small rubber bouncy balls and water beads included. Overall a great out of space play set that can be played with in many different ways.
