Observation doesn't impact experiments. Interaction does. In fact, it is quite difficult to formulate the "collapse" of the wavefunction as a physical interaction and to the extent that we can, the experimental evidence seems to suggest that it is not. This is a common misconception about quantum mechanics, partly because even undergraduate texts conflate the uncertainty principal with observation.

Isn’t the act of observation an interaction?

[DougMerritt]

Sure, but not all interactions are observations, yet they can still cause collapse.
