Why does hand soap "pop" the bubble bath bubbles in my bath?

If you run a bar of soap through bubbles created by bubble bath, the bubbles start popping. Why is that?

    There may be a chemist here to better answer your question, but I'll take a swing at it.
    I know that you can catch a bubble if the catching surface has a coating of the same bubble material. It could be that the chemical breakdown of the two soaps differ. The bar soap would have a different ph level. Maybe more astringent.
    When cooking rice or pasta, if it starts to boil over, you touch it with a little butter (an oil, and soap is an oil too) and it goes down. Or the head on a beer goes down if touched by the oil from your finger. This may be the same concept or could be way off, but it's how I imagine it.

    Just a thought.

    The bar is hydrophilic and the bubbles have water content.

    I don't know the answer to the question but re "you touch it with a little butter (an oil, and soap is an oil too)". Butter isn't an oil and nor is soap.
