Huge bubbles. As I saw them sinking to the floor, I thought "Hey, they should be filled with *helium*." Rev 2.

Those are some bodacious bubbles!

Back in the late 50's, a prof in frosh chem at Michigan Tech made similarly-sized soap bubbles in the frosh chem lecture hall. He did it first with straight hydrogen and then with H2/O2 mix, lit them with a splint. The H2 bubbles went pow, the H2/O2 bubbles sounded about like a 12-gage shotgun.

Then he did the grande finale, after which lecture was dismissed because nobody would hear well for a little while.

I rather doubt that chemlectures are as entertaining nowadays.

The one I remember was the physics prof. He gave a lecture on mass velocity and force. Every time he mentioned mass, he would pick up a black brick on his desk and drop it - CLUNK. He did this several times. When he talked about mass times velocity, he took that item and threw it straight at us. TALK ABOUT GET YOUR ATTENTION. He had switched the brick for a black chalk eraser.

Aww, all we got in high school chem were banana and vomit scented esters.

My favorite physics class stunt from college was purely an accident. I've never seen a prof turn that red before or since. The prof was telling us how it was in the old days, and demonstrated by pretending to fling an eraser toward the back of the class. The only problem was the eraser slipped from his grasp, flew back three rows, and hit a student right in the mouth. The chalk dust left a big white rectangle (he happened to be black). The prof apologised profusely, of course, and excused the student to clean up. He also told him to see him after class. I'm guessing he got an A, and I'll bet that story was never repeated.

Thanks, Ed, I see you are pretty active on halfbakery! I know you've posted on this newsgroup for years. But I haven't followed it much, so tell me, how do you come by the name "Steamboat"? Joel
