how to take this shot?

[PsychoBoy]

I tried to take shots of the bubbles in a lava lamp but it is always out of forcus. donno is it due to the thick glass or I donno how to do it. those with experience taking droplets maybe can helpme out.

this is the best shot so far. this is a bigger picture then crop to so small. dont think I am too near that make it off focus.

Hmmm Try to watch the minimum focusing distance of your camera... and perhaps you can try to use manual focus, the reflection of the glass and movement of the 'lava' as well asthings in the background can confuse your camera's AF system...

BTW, what camera are you using?
