Kickstarter won't resize on mobile (iphone)

I got this all working perfect and tested in browser and it worked fine (even did a 5 star review).

I tested various browser sizes and user agents including iPhone using Chrome. Perfect.

However, when I look on an actual iPhone (Safari and Chrome), the Kickstarter video I have embedded isn’t resized. The youtube videos worked perfectly.

I don’t understand why it’s working when I test in my laptop browser and resize it iPhone size (and switch user agent), but for some reason it doesn’t work on my actual iPhone. In addition, on the iPhone, the video embed looks like it’s cut off on the top and bottom.

Any ideas? Post is here: https://blog.zipscene.com/2013/06/drinkable-pizza-adorable-driverless-cars/
