As we approached our last full day in DC for our week long vacation, we had already dreamed about the next time we will visit this fun-filled-family-friendly city. We hardly scratched the surface of what DC has to offer us. But today, we couldn't go home without visiting the most visited museum in this country - The Smithsonian National Air and Space Museum.
We had planned only one stop today knowing how big the museum is. We started our day early and headed to the metro. After a quick breakfast on the bench along the Mall, we headed to the museum entrance. The line was long but it moved rather quickly. After we got in, we found out that we just missed the 11am tour. A quick stop at the information desk was very helpful. A volunteer pointed us to the 'How Things Fly' room. This room is amazing and perfect for kids of all ages. Kids get to learn about what makes thing fly with an interactive hand-on exhibits. Each one teaches them the concept of air and space. We spent almost an hour in this room alone.
The next stop was to check out the Skylab space station on the second floor. Along the way, we also checked out the Apollo 11 and the Man on the Moon displayed. Do you know that all exhibits in the museum are the original items not replica. It made the experience even more surreal to see all these amazing items that had been out in the space. A line to the Skylab was long but don't get discourage. It moved rather quicky. The kids got to walk through the space station and check out what living and working in the space was like. By the time, we walked through the space station, it was lunch time. We went outside to grap a quick lunch from the McD stand next to the museum. We had a nice time eating there with the structure outdoor that was a great playground for the kids. Then we headed back to wait for the 1pm tour.
The tour started at the Wright Brothers & the Invention of the Aerial Age exhibition. A gentleman who leaded the guide was very knowledgeable and nice. We got to learn about what it took for the Wright brothers to get that first plane up in the air. It was a long tour so it might not be suitable for younger kids. We stayed for half the tour and figured that it was enough for Miss J and Mr. Z so we headed down to the Museum store. The Museum store was a fun place for them in itself. Don't forget to go down the basement to check out the original model of the U.S.S Enterprise Model, used in the filming of the first Star Trek series. I think it was the highlighted of the trip for Mr. Rojo..
By this time, we were done as in.. physically tired and couldn't check out any more exhibits. This museum would require more than one day to fully explore. And we would have to save them for next trip. :) We walked outside to take a quick snack break on the lawn in front of the museum. The weather was perfect. It was such a nice day and everyone enjoyed sitting there and peopel watching for a while... 

We got on our train from our hotel and hopped on the Yellow line and connected to the Red line at Gallery Place/China Town stop. We felt so comfortable traveling around DC with the Metro now that we could figure out our stop or even exchange to different line. Then we hopped off at Cleveland Park stop. The Zoo is actually located between Cleveland Park and Woodley Park stop. But if you got off at Woodley Park, you will be walking uphill to the Zoo instead of walking downhill from Cleveland Park stop. A little tip I received from the Tripadvisor forum..
It was pretty busy at the Zoo today. I guess everyone came out when the weather was really nice. We checked out the map and decided to start from the back. We stopped by the stroller rental booth to rent a double stroller. Eventhough Miss J and Mr. Z are already capable of walking on their own, we knew that the amount of walking today would be too much for them. The best decision we had made that day!!
The Zoo itself wasn't that impressive in my humble opinion. But the kids enjoyed them tremendously. We checked out the baby gorilla, the Ape House (make sure to hold your breath.. The smell was the worst I have ever experienced!!), the Tigers and the Lion.
At lunch, we ate at the Mane Restaurant. It was packed by the time we got our food. The food was pretty decent for the park food. Afterward, we walked around to check out other animals and of course the Panda and the Elephant. 

Once we got in, we waited at the lobby area and checked out the amazing Coke bottle artwork around the world. The detail and representation for each of this bottle is amazing. A short wait and then we were directed to see the short film 'Inside the Happiness Factory'. It was pretty nice and fun short film to give you the glimpse of what Coca Cola wants us to know about their factory..
One of the things I always do when I go to the World of Coca-Cola is to hunt for the Coke sign in Thai. Coca-Cola is pretty popular in Thailand so I'm sure we are a pretty good customer. And they didn't disappoint me when I found a sign in Thai language. It was amazing to see how globalize Coke is.. It's everywhere!
My next favorite part was the Bottle Works. This is where we got to see a real bottling line and see Coke being made right in front of us. Having an industrial engineer background, I love to see all these machines come to life. We probably spent a good 20 minutes watching the Packaging Robot doing his job. And do you know he has a name.. 'Fizzybot' is his name..
After the theatre, we headed to the most anticipate room.. the Tasting room.. This was the room that the kids got to drink Coca-Cola products from all around the world. They group the drinks into regions.. Some were pretty good.. some were not so good (ok.. it was really bad). But you have gotta try them all, right? 
Since we didn't have any other big plan till the evening, we decided to wait. Mr. Rojo was an ever loving dad waited in line for us while Miss J and I walked around and checked out the information room. It was a great place to spend time there. There were so many information of the House and the Senate, short movies to tell you about the history and what the Senate and the House do.. We didn't walk around and check out everything. I went back to check on Mr. Rojo and Mr. Z. The line was moving along but it was still a long way to go. So I took them to have a quick snack at the Capitol Hill cafeteria. It was a really nice cafeteria. I would think we probably would enjoy our lunch time there if we had a chance. But before we could even finish our snack, the fire alarm went off!!! We headed to meet up with Mr. Rojo and followed the evacuation route out of the Capitol Hill. So that was pretty much our Captitol Hill experience. :)
Well, it was a nice day so we took our time in front of the Capitol Hill and the Union Station park. Then we headed to the

It took us approximately about 2 hours for the whole tour. I highly recommended anyone who will visit DC to check them out. After the tour, we walked through George Washington University to take the Metro back to the hotel. By that time it was already dark but we felt pretty safe walking in DC. It's one of the thing that we really love about DC. It feels very safe to walk around even at night in the downtown area. I'm sure there are certain areas that not safe but as far as the popular tourist places we have no issue there.
