Plant has sticky leaves. Ripe seed-pods stay on plant till it rains. Then they explode.
To collect seeds pick the ripe, brown and still closed pods from the plant and brake them open squeezing them by hand.
If you pour water on them their cracking open sounds like fireworks. Seems to be the easier way to collect seeds, but the seeds get extremely sticky in water.
