I just came across this really fun post that teaches you how to develop negatives with coffee and Vitamin C.
Chemistry at work!!
It sounds like something I would love to try one day, with one teeny weeny problem – color films will end up as black and white negatives. Aw. darn.
Still, it sounds like fun. Shall go get a roll of film, dig out my old film camera and play with this one day.

Just a few days ago I asked a friend of mine what ‘B’ stands for when we refer to the different hardness of pencil leads. There’s HB, 2B, 3B pencils etc. I remember in primary school, we weren’t allowed to use HB pencils cos it was too light to be seen. So everyone was supposed to buy 2B pencils instead.
But what’s ‘B’?
Here’s what I found:

Pencil leads are graded by hardness and B stands for ‘Black’. The number/alphabet in front is the rating of hardness eg. H is for Hard while increasing numbers means increasing softness.
Interesting!
Warning: this is just going to be a random set of instructables I saw the past few days.
