Can You Use This TikTok Hack to Make Custom-Size Ziploc Bags? | Hack or Wack

On its surface, this hack seems reckless and dangerous. You heat up a chef’s knife on an open burner on your stove, and then slice through a resealable plastic bag. Supposedly, the heat from the knife will seal the sides of the bag, giving you a new half-sized bag that works just as well as the original.

Now, I would not normally recommend you heat up a sharp object at home until it is red-hot and then start hacking away at some bits of plastic, but this was for science.

Should’ve filled with water to see if it actually sealed.

If you do this you'll fuck up the heat treatment of the knife and it will become dull forever. Use a knife you don't want to use anymore or you don't care about, but never use your good knife.

why do we need smaller ziplock bags?
my answer: lil baby druggie bags

[mattdrifts]

[tashaschmidt]

I literally just googled how to do this. I have gallon bags, but no smaller ones. Trying to store leftovers in portions. Worked like a charm!!! Thank you!!!

The internet is so awesome. I searched for this exact hack thinking I'm weird for wanting to know if there's a way to do this...and here it is.

This is the perfect hack for me! Thank you for sharing! I needed the mini bags to store batteries on flashlights and camping lanterns in case of power outages. This is perfect!

[guidox]

And thats how you fuck up a knife!
Now instead of a stainless steel knife, you guys gotta some untempered ones.
Thats also "science"

I definitely like hack or wack. Thanks for testing things for us, keep up the good work

So totally going to be using this for party favors for my daughter's birthday that doesn't necessarily need a full sized snack bag. It will give better presentation without having to buy more bags

[ginabisaillon]

Hey, not everybody has a gas stove! What's the alternative?

[lunaromamusic]

Perfect! I need to make a long tube shaped bag

[Letthembelightpeaceonelove]

It didn’t work for me 😢 I heated the knife until it turned black but it just cut the bag in half, no seal

[sikz]

This is probably how they are made.... A long strip of bag, that just gets cut down to size by a hot end.

Searched this up For frozen yogurt. Like gogurts. Have tubs of yogurt didn’t wanna buy the gogurt boxes if it’s the same thing .

trying to carry tiny craft beads for sewing onto a plane but you can only take 350 ml of beads with you

You can use a thin wire and a battery. Thats how I cut styrofoam and ziplock bags… small bags are used for distribution of small samples. Just saying… use your imagination.

What if you don't have a gas stove to heat your knife in? Can you heat it in boiling water?
