Dunhinda Fall Sri Lanka with a rainbow

Dunhinda Fall Sri Lanka

Dunhinda Fall Sri Lanka






























To see the breathtaking beauty of Dunhinda falls(210 feet), you have to travel about 5 Km from Badulla along the Mahiyangana road, and walk for another 2 Km (trekking) away from the main road.






Dunhinda is the pride of Badulla and Sri Lanka's loveliest and most dramatic waterfall. This is a part of the "Maha weli" river system, carrying down the waters of Badulu oya. According to the folk history of Badulla, there was a time when the whole area, which is now the Badulla valley, was inundated due to the river being blocked by a Wild creeper which had grown where the Dunhinda begins it's drop. The king of that time gave a commission to a subject to have the creeper removed and save the valley. The task took three months and saw the birth of the waterfall and the safety of the valley.

How To make a simple looping paper airplane

With a little tweaking and practice, you can get this plane to fly back to you. To do this, give it some up elevator as shown. To throw, aim a little above level and launch the plane rolled 90 degrees to one side so it loops sideways and, hopefully, levels out flying back to you. Have fun.

How To make a good paper airplane

I designed this a few years ago and this is my favorite plane. I call this the X-Plane because it is great for experimentation and learning aerodynamics. You can move more weight to the fuselage by varying where the central flap is located, speeding the plane up. You can play with the vertical tail sizes and configurations. You can even flip the main wing folds from the bottom to the top to see how this changes the lift. This design usually needs some flaps to balance it out properly. Enjoy

Safari trip to Udawalawa

Recently I and some friends went on a safari trip to southern part of Sri Lanka. It was a marvelous journey which took around three whole days and we managed sneak through beautiful jungles in Ceylon. On the first day we went to Udawalawa National Park where large numbers of Sri Lankan elephants inhibit. We had 75 elephant sights and most of the time they were in a herd of about 10-15 elephants. We could hire a safari jeep from the entrance and it costs us 2500LKR for the ride which lasted about 2hours. We started at around 10.30pm in the morning and at that time most of the elephants are on the move to their feeding places. There were two very little cute infant elephants and according to our Guide Mr.Siripala from Wild life authority they were about 3 days old. They were guarded by elder female elephants in the herd and also their mother elephants. The herd was very alert on the visitors and elephants in the herd were trying to put the baby elephants in the middle of them so visitors like us could not hurt them.
