I have a Waboba moon ball and a Waboba street ball and they're both amazing so I thought "why not buy a lava ball?" So I got one and it It's amazing. The lava ball measures 2.48 inches, which is the same size as the moon ball. On the other hand, the outdoor ball is 2.25 inches. So let's compare the moon sphere and the lava sphere. The lava ball is slightly heavier than the moon ball. While the moon orb bounces in random directions (making it harder to catch), the lava orb is round and almost always flies where you want it to go. The Lava Orb is also slightly more resilient than the Moon Orb. The lava ball changes color when exposed to the sun's ultraviolet rays for about 20 seconds (in direct sunlight). I have a laser that has the same frequency as the sun's ultraviolet rays. When I irradiated the "Lava" parts with light, they turned dark red! I would definitely recommend this ball to anyone looking for a ball that bounces really high. It's a bit heavy, but like I said, it bounces VERY high. If you want something lighter but still bounce high, get the Waboba Moon Ball (https://www.amazon.com/Waboba-Moon-Ball-Colors-Vary/dp/B00IDZZ96Y/ref=sr_1_2?ie= UTF8&qid=1533338776&sr) . =8-2&keywords=moon+ball%5C). If you want something smaller that looks REALLY cool and still jumps pretty high (but is harder to catch like the moon because of its edges) then I recommend the Wabob street ball (https://www.amazon.com/).

The "Lava" part is really cool and interesting to look at as it changes color in just a few seconds. Every Waboba ground ball is amazing. When you need an awesome ball anywhere, get the Waboba ball.
