Ep. 2 of Let’s Engineer Some Sh*t: Cooling Blanket Edition 🧊
We’re gonna craft an icy blanket using 2 thin blankets, some velcro and a few reusable ice sheets. For any folks who either dont have an ac or may not be able to afford the electric bill that comes with an ac, this is a simple diy solution that should cost you ~ $20-30. 🫡
Ice sheets: 3 pack - $12 or 6 pack - $18
Velcro: $8
If you haven’t used these ice sheets before, no worries, they’re super easy to use. 😌
We just soak this fabric side in water and you’ll see each of these cells fill up with water. Then, we pop it into the freezer. Now, we’re gonna take 2 blankets, thin throw blanket would work well, you dont need to use your thickest blankets for this. Then, we’re gonna create a middle section for cooling using our velcro. 🙂↕️
If you want to mark your sheets so that the line up, you can. The main thing we want is enough space to fit 3 ice sheets. If you want to use all 6 you can, but this blanket gets really cold with just one or two ice packs, so we recommend you just use the 2-3, while 3 more freeze and swap them out once the first 3 melt. 🧊
From there you’re going to place your velcro onto the blanket to create a pocket for your ice sheets. You dont need to make full rectangles, if you want to be sparing with your velcro, as long as you make sure your corners of your ice sheets are secure. Repeat the process with your second sheet and make sure the opposite velcro strips line up with the pacement of your first ones. 🤓
One thing to be mindful of, there will be some condensation after a while and it might make your sheet damp, so make sure you use your fan to help evaporate some of that condensation and cool you further in the process. ❄️
Of course, this isnt a perfect solution for hot summer months, but its an affordable, easy and reusable solution that wont hike up your energy bill. 💡
And, after testing it out ourselves, we are sure it will help beat the heat. 🌇
