Why does the scale need to be upside down? Why not just use it the right way up?
if you can get the experiment to work well with the coke bottle upside-down that would work. problem is we haven't tried it to know if it works upside down yet or not... so who wants to do the trial and tell us the results?

I meant why not just put the bottle on the scale the right way then add the mentos. Surely this would also work?

Can't see a signle reason why it shouldn't.

that's a genious plan, just cover the scale with something so it doesn't get soda all over it. tonic water will work way better than soda, it is more carbonated.

because you would get no reading. it would only weigh the bottle. if you have the bottle the right way and put the mentos in and the scale above that you can determine the force that it pushes on the scale

The world is like an atom. The not-quite-as-intelligent people are the nucleus all packed together sharing a common...everything. We, we are the electrons. Granted we're not as smart as these engineers and what-not so we're most likely in the first orbital, but we're the electrons of this giant atom. We all have differing intelligences and ideas and we are separated from the nucleus which makes us better because no one really cares about how a nucleus acts. It's the electrons that make chemistry, except for nuclear chem, of course, which I am a big fan of.

I disagree.

Sure if you place the bottle on the scale it will weigh the bottle. Now you put the mentos in the bottle and soda shoots out the top of the bottle. If I am correct the soda will exert a force on the bottle (and vice versa) which means you should get a change in the reading on the scale which you could equate to the force. (Newtons laws and all of that A exerts force on B etc etc)

it's the same thing, whether it pushes down or up.

it would work but for your way i think you would need a board to act as the ground to measure the exact exerted force instead of shooting into free air it has a little extra kick

i see what you're saying now, but the force of the soda pushing out will be the same either way.  :o

the board acts as the ground so the bottle pushes against it instead of the open air which would give an incorrect reading
