I've seen a wax candle pass through a wooden door, having been fired from an air gun. Left a very neat hole and, although compressed a bit, the candle looked remarkably undamaged. Amazing what the right amount of kinetic energy can do.

That reminds me, ipearse.
Every time there is a strong hurricane in Texas, the papers will have an obligatory photo of some ordinary object that has pierced a telephone pole. Items that you couldn't drive through a pole using a hammer. Something like a small diameter stick or a 2X4 that is visible on two sides of the pole.

Amazing what the right amount of kinetic energy can do. Ah! I was going to mention that but could find no web record. Whether it was the same one or not, I remember it was a candle shoved in a 12 gauge cartridge and fired from shot gun. The candle tumbled but made a very neat candle shaped hole in the door. Not sure if it was on that program in the early 80's late 70's on how stuff worked? One of the guys was an action film and TV prop maker etc. Got to play with all sorts of goodies.

Amazing what the right amount of kinetic energy can do. Well this is where the CTs fall over. They talk about hardness and resistance, but the real issue is energy and time. If the moving object can exert an impluse of energy over time at a stationary object in such a way that the pressure applied is greater than that objects yield point, then the stationary object will break. It is quite possible that the moving object will take a lot of damage too, especially when the object it hit is more rigid, but if the energy is suffiecent, it will pass through.

It seems that CBB has realized that his arguements are trashed.
Science wins again!

More like he's moved on to the next webforum hoping that they'll be less knowledgable

Or at least less logical.

Logic is, of course, the beginning of wisdom.

[insert obligatory reference to Spock here] That's what I had in mind when I posted that.

GLP has pop-ups and stuff; if you use I.E. I recommend you have it in your "restricted sites" zone. The link is to a thread on GLP (a forum where one does not have to register to post) where someone of the same name as this OP has posted.

Ah. Promoting another site. Looks new? It is the one mentioned in the link in the link. If that makes any sense.

From holographic planes to giant glass Martian worms, eh?

Oh dear. My first real debunking effort when I joined BABB (as it was then) was the glass worms of Mars.

I saw it at an exhibition at the Science Museum in London way back in the early 70's on a school trip. They did a lot of really excellent demonstrations, but that's the one that sticks in my mind. The otherone that comes to mind is the one my father used to do at HMS Excellent (Royal Navy Gunnery Training establishment on Whale Island) when demonstrating the dangers of "blank" rounds, by firing a hole through the base of a galvanised bucket using a rifle with a blank round in it. The students were all suitably impressed...
