High speed photos
These photos ware made in 1977.
The photos were made with electronic flashlight in a darkened room.
The timing is crucial. The soapbubbles burst because they are hit by a
doplet of salted ethanol. The droplet passed two golden contacts.
The signal this generated was amplified and delayed with a TTL MMV
before it trigger the flashlight.
By experimenting with the delaytime (≈ 5.8 mS)
the following results were achieved.
Three photos of bursting soapbubbles
The diameter of the soapbubbles is 14 cm.
Exposuretime ≈ 60 µS.
