Please help me inflate and pop the baloon

[dv2000]

Hi,
I have the scene attached here.  Can anyone please help me inflate the top of the balloon (alien plant)  and pop it after it gets 3-4 times bigger after inflating for 50-60 frames. Also the plant is supposed to wiggle at first using force gravity but then  it wont inflate anymore.  Can anyone  help?  Thank you !   I really dont want the stem to inflate but then the top goes away.

Not sure to understand what you want to do.
Basically the plant needs to wobbling at the start for some frames and than only the top part needs to inflate and than explode\pop?

I'm not sure that it can work but i think that you can approach this like the flag example in the tyson scenes.

The steam is one event and the top is an other event binded to the first one, so you can have more control on wich part inflate and when.

The only thing that i do not really know how to do is changing the lenght bias to make it 3-4 times bigger, i'm trying to animate lenght bias but nothing change.

Late I will post some screenshot to be more clear.

I Attach You a file and some screenshot of a quick test that i've done. The Pop part is missing cause i do not have time now to finish the test.
Later I will try to do it.
I've also simplified a bit the geometry cause is too heavy for my workstation

Hope that this can help you. I'm pretty Noob so maybe is not the thing that you need, or the right way to do it. but I've tried.
