I don't know why, but they will not play for me period on iPhone or laptop. The screen will be black & have the button to click like when normally watching a video, but that's all they will do for me. Wish I could as I use tubes a lot & have tried hand dipping & think I could get some great info from them on things like how long to keep dipped in hot plastic etc. when doing the first dip & would really be interested in seeing how he done the horizontal dipping to cut down on wasted plastic. Thanks guys & if anyone figured it out let me know. I appreciate the help. Is there any way that they could be emailed & it would let me open them?
