GENIUS COOLER HACK | $22 Bucks 

Melting ice and ice water is always 32°F, so no need to take temps until after all ice has melted. Until then the real test is how much ice is left. Otherwise, great test. Thanks!

I have the same cooler, I took off the lid and placed it on a flat surface to help the foam travel inside the lid. Second, there's a cap/plug near where you drilled the hole, i used the existing plug hole to stuff the foam.

ARTIC WAS A BIG RIP OFF. Glad you saved us $100 bucks. ty

I couldn't see how you did the silicone gasket. That would be helpful to show.

You put the blue modified one in the middle where it would have two sides protected by the other two coolers. So I would say you should do this a third time with at least a 6 inches of separation. Also dead airspace inside a cooler should have not effect. The dead air in the cooler will be the same temperature as the ice water combo. So the heat flow through the walls should only depend on the R value and the area of the inside of each cooler. They all looked pretty similar in size.

I am pausing this video at 7:24... my prediction is the blue cooler in the middle will retain the ice longer because it is insulated on two sides by the other two coolers. I will now resume watching the video : ) Edit... I quit watching at 7:45 already know the results...SMH

Hello ...nice video mate I have an igloo marine ultra Am afraid I need to use my drills too... Let me ask you, why you choose to make the holes inside instead outside.... avoiding microbio.....points? Keep cooling !!!

One large hole was a mistake. You need multiple small holes barely larger than the foam can's spray straw. The foam was shooting right back out of that single entry hole because all the small volume of foam did was compress existing air within the lid. You need not only air escape holes but also holes to allow you to reach every region within the lid. Sorry to say but that alone invalidates any further comparisons and testing using that cooler.

I take it the wife won't let you have your guns in the house

The cooler in the middle is insulated by the other two coolers beside it. The air circulating around the outside coolers will melt ice faster.

I believe it’s a fail of a test since the unmodded cooler is different then the modded one. They should be the same style for best results. I have seen other videos where they used two identical coolers and foaming the lid made it work worse. The modded cooler in the video also has the bulk of the bottom off the hot ground a little due to its design, which would help, unlike the other coolers.

Wouldnt the foam and silicone be bad for your health even after it cures ?

Mmm Lager. From my home state, hope you drank the cold one after the video :)

The blue top should be a place to fill cover with water leave cover in freezer so it becomes a block of ice

He switched that blue cooler cause the foam screwed it up. The microfone issue was alie to make the switch. LoL, before he got started. I love these vids where people use a product they're not experienced with

putting your modified cooler between 2 coolers and another plastic box helps with isolation...

I wonder instead of the spray foam if saltwater inside the walls would keep things cooler? Seeing that saltwater has a lower cooling point. Anyone tried this as an alternative? Thanks for the info.

I recently pulled two cheap coolers apart both had gaps in the base insulation one was in two pieces with a gap and the other had a two inch square gap for a non existent drain a quick check with a strong light would reveal any gaps,I got a 30% increase in ice retention by fixing the gap and foam filling the lid regards Mike

Do the red one too!

that's a great modification

Physics tells you that insulating the bottom of the cooler will be more efficient than the top. Do both top and bottom for greatest bang for buck.

Super helpful. Thank you!

For anyone out there, I've tried this hack and it does NOT work at all. Buy a decent Ozark cooler. 95% Yeti performance at half the price.

I waited for the foam to dry before cleaning up. A lot easier to clean. Also use more than one hole to spray the insulation.

You're an extremely practical web video; couldn't make it without ya!

Ive seen other videos way much better than this, his work was a mess & sloppy, not showing the rests of the clip & suddenly its done?

Oct 1 is bow opener here in Southeast IN

Wish you had told us the temperature reading of each cooler instead of saying "pretty good"! What does that mean? :/

So why does red coolers top have the same drilled hole that the blue one does.

That lid on the red cooler is modified. You can see the drilled hole in it and bumps on the top where the foam is bulging because of the indents on the underside.

How is that worth the investment?? To have a few more ice cubes?? So you wasted more money, and time for very little results.... when you should just get a yeti, or one comparable to a yeti. Insulating the top, and adding a seal is not near as important as having a cooler with quality insulation inside all of the walls! Because that’s where insulation is most important. There, I just saved all of these RU-vid cooler hack channels a bunch of time, money and effort! Not only that, but doesn’t anybody look to see if somebody else has made the same video before they waste their time? Because there are quite a few videos out there exactly like this and all of them have held the same results, but the ones that compare there “improvements” to a yeti, no matter what improvements they make to cheaper coolers, it doesn’t come close to a yeti, Because cheaper coolers are cheap for a reason! And yes I know a yeti is more expensive, but you’re going to have these coolers for a good amount of time so the money you waste on ice (and possibly ruined food) for these cheaper coolers, you could’ve bought a yeti!

Silicone casket, where’s the how to?
