Interesting, to say the least.

I approve!

Adding video to channels (Howto) - requested by calvados.

Considering the cost of a vacuum sealer I expect this man to turn up dead under suspicious circumstances within days. I'd sooner mess with the Yakuza than the vacuum sealing product industry.

Well, it's not really vacuum sealed. It's more like he melted thin plastic onto the food, I wouldn't recommend using this as a common practice since, after all, plastic is made from petroleum and contains a considerable amount of carcinogens when ingested.

Suddenly there is an explosion of cancer cases! Doctors are baffled...

moron alert. this is not vacuum sealing anything.

it's also not geek, cooking, or howto-anything besides poison yourself. it is science, but only in the way that accidentally deep frying a still-frozen turkey is science.

I sat here for a couple minutes, wondering "How the fuck can you vacuum things with a ziplock bag, and why the fuck would seal food be in a microwave?"

Then I watched the video.

Then I got it.

And I laughed.

*eia ?
Seriously kids, don't try this at home.

Invocations (eia) cannot be called by charliem because charliem is not privileged - sorry.

What great, time-conserving way to artificially increase the content of carcinogenic dioxins in my leftovers!

This is sure to decrease my life expectancy by alteast 10 to 20 years, thanks Metacafe!

(As many people have already stated in the previous comments, do NOT do this)

He's not melting the bag. It works via condensation. When he heats up the food, steam fills the bag. Then he seals the steam in the bag. Given a fixed number of water molecules, the vaporous state will occupy a dramatically larger volume than the liquid state. So, as the bag cools and the steam turns back to liquid water, the bag collapses.

This happens when I microwave cubed potatoes with cling wrap over the bowl. As soon as I break the seal, the cling wrap quickly tries to smother the potatoes.

Things frozen in ziplock bags stay fresh indefinitely, without the nuking. What value is the microwaving supposed to add?

I don't think he melted the plastic... My guess would be that since a microwave excites water molecules, thus heating them and cooking food, the heated water is expanded and turned to vapor. When it cools, it condenses back into water and is re-absorbed into the food, doing something similar to a professional vacuum sealer.

Id say even if he didn't melt the plastic probably not a good idea to do this.

So... Looks like people are still willing to voice opinions without doing preliminary research first?

In the age of the internet rumors may out-number facts, but the facts can be looked up.

I'm not convinced there is much wrong in this method.
