I have wanted to make a time lapse video of this for a while now. Today I finally had the opportunity.
Unfortunately the capsule did not contain any seeds but it shows the opening and closing mechanism nicely.
The frames jump a little at some points, but I still think it's a nice view.
This whole thing happened over 80 minutes, I took a picture every 15 seconds.
The opening happens quite quickly but the seed capsule takes its time to close itself again.
