How to Make a Pocket Capsule to Keep You Warm Wherever You Are

Hello!

In this instructables, I'm going to share with you an everyday hack that slips into your coat pocket!

We now see the innovation of heated coats which makes you want to have one, especially during the winter when you even shiver in your coat. But unfortunately, not everyone can afford to buy one.

Also, the problem is that I had a lot of trouble getting rid of the glass jars because I told myself that they could always be used for a few things, so I found a good way to recycle them!

This tip will therefore warm up your coat and also you who are in it with it!

Supplies

And no no no! you don't need to go to the supermarket to buy the necessary supplies, just rummage through your kitchen drawers to find a small hermetic jar, and made of glass so that it can withstand the heat, then add go to your garden to look for some small stones that will fit in the jar.

The stones will keep the heat in the jar much longer!

Step 1: Hermeticity Test

To ensure that there will be no water leaks into our jacket, we will make sure that the jar does not have any leaks.

For this, we will simply fill the jar with water, close it, turn it upside down, then wait for some time and if there is no water coming out of the jar, if it's good, then we can continue with insurance.

Step 2: Assemble the Components

So we're going to take the jar and the stones and put the stones in the jar.

Step 3: Add Hot Water

To give heat, we will put hot water in the jar.

All that remains is to close the jar and that's it, we have our heating capsule.

Step 4: Jar Temperature

According to our results, the outside temperature of the jar is therefore around 32.3°C for water around 70°C inside. If you put boiling water inside, the temperature of the jar will be higher and will give you more warmth.
