Mount Bromo-Mount Ijen-Bali

It's been a while since I last blogged, and that's primarily because I was kinda busy with work and life and erm, preparing for this trip (my friends and I have been preparing for this trip since February, but we didn't actually prepare for it until a week before the trip).

So yeah, here's a brief summary of what to look out for in these three places.

Can You Really See The Great Wall Of China From Orbit?

Legend has it that the Great Wall of China is the only man-made structure that can be seen with the naked eyes from orbit. 

However, according to Canadian astronaut Chris Hadfield, who had just returned from a five-month mission aboard the International Space Station, it is not possible to see the Great Wall of China from orbit.

So you're telling me that it is not possible to see a 8850km-long man-made structure from another man-made structure parked 330km above the surface of the Earth?

If You Cut An Earthworm In Two, Will The Parts Grow Into Two Separate Worms?

You may have been told as a child that an earthworm will regenerate into two separate worms if it's cut in half crosswise. At least I was.

But I never really had the opportunity to experiment with a real earthworm--all the worms I dug up from my garden ended up as fishing bait.

Like most other animals, the humble earthworm has a head and a tail. Since earthworms have no eyes, the only way to identify its head is by looking at its clitellum.
