Inventions, objects that make our lives much more easier.
Have you heard about a spy pen, or how about a car that runs on dry cell battery's? Lets go back to the nineteen hundreds when the airplane or the camera was invented. Without airplanes, how would we be able to travel across the world to meet family members, or just travel? And without the camera, how would we be able to capture our precious memory's? That all comes to mind if you could imagine what the world would be like if inventors like Albert Einstein, or the Wright brothers. Now if we fast forward into the modern twenty first century, you can see how much the world has turned around. YouTube, and Facebook are inventions that have happened on the the computer, while apple has created the iPhones, and the i-Pad. One of my personal favourite inventions is the spy pen. It has an Mp3 player, recorder, video recorder, and you can take photos. What I found that was simply amazing was that a college team in Japan created a car that ran on forty dry cell battery's, that reached a top speed of sixty five miles per hour! An invention I would want people to invent in the future is a car that can drive itself, so the blind could get from place to place. What are your favourite inventions, and what do you want people to create in the future?

Columbia, the Journey Beyond.
Hi all. I know I haven't posted in a while since I was busy. I am going to try to keep up and post at least once in two weeks. If you want to post something on my blog go to my website. I put a lot of pictures that I took on Facebook.
When I first started our trip to Columbia, I thought I wasn't going to like it there, and it was unsafe. I found out I was wrong. Columbia is a charming place with many warm hearted people(this can't be said for all South American country's though). Our flight to get there(San Francisco to L.A, L.A to San Salvador,and San Salvador to Bogota) was 20 hours, including the time we slept at the airport, and waited. It was long and boring. I only had a lot of fun on our last flight, which we took Avianca Airlines, and got to have a personal T.V. When we reached Bogota, we found out that the Airline(s) had misplaced our baggage! Luckily I had one extra T-shirt left in my carry-on bag, and it was our last change of clothes for the next four days. I gave the T-shirt to my brother, Anav, because of his skin issues. Our hostel that we stayed in was very nice, and I felt welcome there. A good part about the hotel for me was that it had Internet access, and I could work on a school project that I took there to complete. There was a lady that worked there that spoke English, and helped us a lot during our stay in Bogota. Over the next few days, we visited the gold museum, and had fun hanging around downtown, and went to the top of Monteserrat. Personally, I don't think Bogota is very safe after 9 or 10 pm. We met a man that was mugged by three men and lost 50,000 Colombian pesos (about $25), but he was coming back at 10 in the night, alone. We went to a cathedral made of salt (it was pretty cool) about an hour away from Bogota for a side trip. It was called Cathedral De Sal. On our last day in Bogota, our bags came in the night, lucky for us!
From Bogota, we took a bus to the city of Medellin(pronounced Meda-gene). The bus ride a long twelve hours. The thing that REALLY annoyed me on the ride was that my brother kept on sleeping on my lap for a full eight hours! And believe me, when someone lays on you for that long, your leg starts to hurt. When I pushed him upright, he fell right back on me again. We arrived at about 7-8 in the morning. We stayed in another hostel called "yellow house." It was nice. Two dogs that the owner had kept fallowing me everywhere I went. One of the dogs kept on trying to get into our room, since he liked to lay down on the balcony that we had. The room had one bunk bed, and one queen bed. Medellin was an amazing city, my favorite on the trip. Their public transport system was simply amazing! I have never seen anything like it. You can take the metro almost anywhere. From there, you can connect to the cable car to go up a hill, or to the bus station right next to the metro. In the cable car, you can see Medellin; the skyscrapers looked like puny ants from up there, and the view was stunning. We went to so many stations, and the whole price was about (U.S) $2.50. When you are on the the cable car, you can ride it as many times as you want for only 75 cents! We went up the cable car a few nights before Christmas, and you could see so many lights. We went an other night to a type of "light carnival", and they had a whole row of lights down a river. We couldn't even see where the end was. I do admit I got a little annoyed from riding on so my transport systems, but it still was very fun. I definitely recommend you to put Medellin on your travel list.
After Medellin, we took a flight to Cartagena, which is mainly known for its beaches. At night, the old part of Cartagena is very festive. People sing, dance, eat, and just hang out. The coconuts there are really good. I love the coconut water, and meat. The place we stayed in had a small pool, fish pond, hammocks, and a T.V. We were located near the beach and the fort that surrounds old Cartagena. It isn't a very far walk to get to the dock, square, or any other place in Old Cartagena. We also went to see another fort, and the view was spectacular! In the fort there were many tunnels, and we had lots of fun exploring them. We took a small day trip to a beach called Playa Blanca, which was supposed to be a really good beach. In the ship, I got seasick because the boat was turning a lot, and we were on the bottom of the boat. When we got there, we ate a typical lunch with had chicken, or fish, coconut rice, salad, and a small cup of limeade. The water was very warm there. Over the next few hours, we went on a ride where a motorboat pulls a banana shaped thing(I have no idea what it was called), and me, my brother, and my dad got to ride on it. We also went on a jet ski with my mom and brother. After sometime, it started raining like crazy, so we headed back. The next day, we went to a 15 meter high mud volcano, for a mud bath. When we went in, the mud was so warm, and it felt as if you were floating on air, because the mud was so dense. After we got cleaned up, we headed back to Cartagena. We played on the beach a lot too in Santa Marta, a town about 3-4 hours away from Cartagena. The hotel that we stayed there wasn't as nice as the hostels, because you can't really meet and talk to people. We went to a place called Taganga, that was a 15 minute ride from Santa Marta. The water was nice and calm, and perfect for swimming in. The next day, we were supposed to go to the beach, but a lot of things changed. First of all, we had to walk on the road to the trail head, since the bus couldn't pass because of the mud. Another bus's wheels had gotten completely submerged in mud, so they couldn't take it out. Once we got there, we had to walk through lots of mud that made your shoe stuck every time you step into it! We also saw about 999 quadrillion red ants, plus two or three huge spiders. The worst part was that the walk wasn't short. Imagine walking through all that icky mud!! This wasn't anything like the mud bath, and Anav hated it a lot. We headed back to Cartagena after a couple days at Santa Marta.
After our revisit to Cartagena, we went back to Bogota. We were supposed to get a room at the same hostel we started out with, but we had to cancel, because dad didn't read the plane ticket back home properly, and he read the arriving time(6:00 am) instead of (1:00am). So, we camped out at a gigantic mall from 2:00 till 7:00. It sold everything there! The humongus supermarket was small compared to the whole mall! After 7:00, we went to the airport, and slept there for 4-5 hours, until the boarding began. Once we landed in L.A, we had to take another flight to San Francisco. When we landed, we took a bart train to another station, and then switched over to the bigger one. After that, we took our car home, and ended the trip. All in all this trip was pretty hectic, but still very fun. These memories will stay in my head forever.
