Potato Chips: fail???

I made some homemade chips, but forgot to spray with nonstick spray, I think they burned. I bet I left them in the microwave. I'm not going to give up cooking potato chips, I'll try and try until I get it right! They are very crispy, It's hard to eat cause the chips are hard. I bit into one and tasted the burn. Well, apparently 5 minutes was a little to long for me!
