Essential Forces Fountain
There is something so inherently dissatisfying about this fountain. Yes, you can play in it, and yes, it does appear lots of folks bring their kids there, but it's so... blegh. It taunts you. You want water, and it toys with you. Grrrrr!
Here's some official info that the Rose Garden Arena sends to potential clients:
Your guests can enjoy the sights and sounds of the elliptical water and fire feature, "Essential Forces"- a one-of-a-kind fountain composed of nearly 500 kinetic water jets. The two pillars of water and fire welcome guests to Rose Quarter events with its magnetic aura.
Here's what Atul666 wrote about it in Cyclotram, which I think sums up my feelings quite nicely:
One of those timed, computer-controlled fountains beloved by casinos and some (but by no means all) small children (and by them only on hot days). Actively anxiety-inducing, which is really remarkable for something made entirely of running water. And that's even without the "fire feature" running, which only happens before big sports events at the arena.
