[Charcoal + Potassium Nitrate + Sulphur] when ground together in the right proportion, make … great photos!

Here is a scene from chemistry class.

 

First, we made charcoal by heating hardwood without oxygen.  This produces a lot of smoke, but in the end, all that’s left in the test tube is charcoal sticks.

Second, we ground the charcoal to a powder, and added a some potassium nitrate and sulphur.

Here is a spoonful of the fresh made black powder

Upon touching a hot coal to it, it ignited and combusted with a lot of smoke!

Quite bright!  This is a neat photograph (taken with Droid X)

Panoramic of Winter Scene

This one was comprised of about 87 overlapping photographs.

Eli took his new tripod, on a bitter cold day, and set it up on the “top tier” of cleared ground, capturing about 270 degrees of the scene.

Again, we used Hugin to stitch it together.

And lastly, here is the recorded “activity” in the new Home School software.

360 Panoramic from the Top of the Hill

I took about 45 photos today, freehand, with Eli’s FinePix point-and-shoot digital camera.  The camera isn’t in top shape, and the light of the sun really washed out some of the shots, which was propagated to all shots by Hugin while stitching.

I would imagine that if I knew more about Hugin, that I could prevent some of this.

Regardless, it’s a pretty cool picture.  Zechariah is in it, if you can find him!
