Every four years theres a new ball for the World Cupand every four years players are unhappy with it. Maybe its too light and has too much lift, like the 2002 Fevernova. Or maybe it wobbles unexpectedly in the air, making it harder for goalies to predict its motion, like the 2006 Teamgist. Or maybe the ball suddenly changes speed, dropping out of the air and causing accidental handballs, like the 2010 Jabulani.
At the World Cup level, these tiny changes in a balls aerodynamics can legitimately impact a teams performance, so the intense scrutiny of the World Cup ball is perhaps to be expected. You could argue that its the most important piece of equipment in the most popular sport in the world, says John Eric Goff, Professor of Physics at University of Lynchburg.
Adidas designs every World Cup ball, and on top of being a big seller for them, engineers at the company are constantly a little closer to the perfect ball, Goff says. The ideal soccer ball is a pimple-covered, perfect sphere, its surface just subtly textured enough to keep the airflow around the ball slightly turbulent. Unintuitive as this might sound, the ridges and pimples on the ball make it more aerodynamic, helping the ball to fly through the air more stably.
The Telstar 18, the design for the 2018 World Cup in Russia, is as close to a perfect sphere as you can get.

Face paint time, pic 2 (this is how to walk a dog), pic 3 (when my daughter picked the giraffe face-paint the woman said she just added that option the day before and this was the first face she painted with it. Then she said she remembered us from last year. I told her see you next year!)
Feeding time at the Zoo, pic 2, pic 3
BTW there were a lot of people with dogs. I even seen a few with three and four dogs. All dogs were kept on leashes.

I used my daughter's name a few times to ask her to come and turn a little bit when a pooch came to us and then the owner told me she has the same name as my daughter, pic 2
Luna looking at fish, pic 2, pic 3
Luna looking at blood thirsty kangaroos (don't let them fool you)
Luna watching the Dog Show (they did impressive tricks including all barking together on command. Which set off a bit of mayhem).
There were a lot of dog merchandise stands.
There is what's called a Castle on the Zoo grounds that you can rent for events, pic 2, pic 3, pic 4

BIG THANK YOU to my daughter for being in many of the pictures!
She is an aspiring child model/actress.
Whew that was a lot - now I am hungry like an elephant!
