Set an alarm clock to go off after 29 seconds thus knocking an extremely sharp pin on the balloon and popping it!!

Yes?? I think so!

How would this alarm clock knock a pin into the balloon?

Is this actually a difficult task for you to comprehend?

put a cat toy inside the balloon, place it at a distance that would take the cat 30 seconds to run, and video tape it too, because it WILL be funny.

Rube goldberg machine ftw!

From a purely technological point of view, I would say use 18 pool tables in succession, each covered in a series of intricate patterns of matches, which together form a treasure map depicting a fantasy island in the south pacific. Naturally, it will take exactly 27 seconds for the matches to light from one sight to the other, thus leaving you 3 seconds to pop the ballon with a pin.

Old fashioned alarm clock with bells that vibrates and then knocks the pin onto the balloon. Or you could use a phone.......


Or a timed bomb


Or dress your friend as a robot and pretend you built him and then get him to burst it.


Wow. I've really outdone myself

this is such pure genious, i will definitely NOT try it out

Make a seesaw. Fasten a small cup to one end (cup A). Fill it with something like sand. Fasten an empty cup to the other end (cup B). Use a third cup suspended above this cup filled with sand. Make a hole in it. Put enough sand and a small enough hole in this cup so that it leaks out for 30 seconds, when the amount of sand in cup B is enough to swing the seesaw down. Make sure you have a needled underneath cup B. And a balloon. It will pop.

THE END
We're only strays.

an automatic pump

set up an epic trail of stuff to knock it over

or wait thirty seconds pop it yourself

wow this does make you feel good

well... I guess you could use a chemical reaction that takes 29-30 seconds that produces enough gas or heat to blow up a balloon.


That's IF you're allowed to use chemicals.

You get a water container, (pretty large) and put the balloon in it.

Create a lid that fastens to the container and cover the underside with pins (magic tape them on or something)

Cut a hole in the lid. You then have a water pouring device like this:


That you open so that it takes 30 secs for the balloon to reach the pins and be popped.

Ouch. My guess is a CPU to a Roland synth? (I saw Roland in the URL)

Who's to say the balloon won't just rest on the pins? I like this idea though.

If you made sure the pins were placed at a pretty low density you'd be pretty sure to pop the balloon (provided the balloon was blown up pretty far)

or you could use needles held in place by clay or similar, they'd be sharp enough to pretty much guarantee popage.

The balloons will be blown up to a 9 inch diameter. Clay would be a good holding substance.

erm moblie phone> set its timer to go off after 28 seconds> set to vibrate> attach a pin to the bottom> put on slanted surface> put balloon underneath

when the mobile vibrates it will slide along the surface and drop onto the balloon

i just tried the first bit, without pins or balloons

you have a see-saw type thing where the balloon sits under one arm of the see-saw (which has pins or needles mounted on its underside)

The see-saw is balanced by either bottles of water or sand.

make a small resealable hole in the opposite bottle so that after 30 secs enough material will run out so that the balloon pops. You just need to calculate how much material you need for 30 secs to pass before the arm pops the balloon.

You won't have the problem of my previous idea where the balloon might just rest on the pins because of the weight on the see-saw arm.

I weirdly having studied electronics understand most of that... *scared*

Its just a load of ICs with AND and NOT gates, ooooo some operation amplifiers as well.

EDIT: lots of binary counters as well.]

EDIT2:

TS, If you have the facilities you can design a program using a PIC which when switched on will wait for 30secs it will then operate a motor with a pin on it after then it will loop continually.

That should work.

just tie a regular 30 second timed fuse to the baloon and light it, make sure you time the fuse yourself and make sure it burns at a consistent rate. Or rig a timer to a model rocket igniter.

what i got out of yours was that you wanted the bell of an alarm clock to hit a pin into a balloon. sorry.

Do a preliminary experiment of timing how long it takes for a 1m length of string to burn. Work out the speed of the flame in m/s by doing 1/time taken.
Use the equation Speed x time = distance to work out how much string you will need to make a 30 second fuse
