This video is really interesting. It demonstrates that our observance alone of quantum particles (electrons) make them behave differently.
Electrons are being shot into one/two slits. When we measure what an electron is doing, it goes through one slit, but when we don't look and just look at the pattern it creates, it splits into two, goes through both slits, and interferes with itself.
It doesn't do this every time, but actually does four completely different things at once. It goes through neither slit, only one slit at a time, and both slits at the same time. All this happens at once, which seems impossible.
You are on the right path.
The delayed choice quantum eraser experiments are even more bizzare when viewed from a perspective of materialism.
We may not have a good grasp on reality but we know for sure materialism does not provide a good working model of reality.
