Popping a balloon INSIDE another balloon!

I remember reading posts about doing this way back, so I got some clear balloons and gave it a try. This is a really cool physics experiment, and I think the only possible way to pull off popping a balloon inside of another balloon is using intense light. I also lit a match inside of a balloon, but the match quickly runs out of oxygen and goes out.

Enjoy!

I remember as a kid at the Science Center in Toronto they
demonstrated this.

Wonder if its still part of the 'show' they put on with that
monster of a laser they used to have..

Used to go once a week and made sure I was always on time
for the laser demos :D

That and typing profanities into the talking typewriter,
holding the repeat button down and hiding off to the side
while parents walked passed having a machine swear at them :eg:

What kind of laser did they use?

To be honest I cant remember... This is now 25years after the fact..

For the ballon demo IIRC was green, probably argon under 30mW. They'd place
the balloons on what looked like a large funnel with the beam facing up.


The beast they had was built into a cabnet approx 10+ ft long. The tube
was exposed from the side and could be viewed like a large HeNe tube.

The beam dia was in the area of 6-8in and used a brick to terminate.
Id imagine the glass in front of the demo area for this laser was there
to block.

Now that I have kids its a perfect excuse to go back and refresh my
memory :)


Found a few pics... These look old so im sure the lasers are the same,
but cant find much info on their website.
