slit experiment results in quantum mechanics

Need an explanation of the effect of the slit experiment. If you know the electrons coming thru the slits then they behave like particles but if you dont know then they behave like a wave.

If you capture the information but destroy it then it still acts like a wave.

But , what happens if you capture the information, look at the results then look at the information. does it change from a wave to a particle. If you take a picture of the results before and after then they would be different? this QM stuff is confusing enough but this reality page has me buffaloed. Before long I will be pushing a toaster thru the slits.
