This is a homemade bath sponge made by reusing household items such as garlic netting and leftover soaps.

I was motivated to make this since I had a lot of soap leftovers that were simply too small and unusable for soaping. I had a huge pile of them and I realized how much waste I am producing for not using these tiny soap leftovers. Combined together they can make a usable big soap bar, yet melting and reforming them int he microwave didn't work out, so I came up with this clever and unusual solution.

Step 1: BoM

Garlic Netting
Soap Leftovers
[Optional] Ivory Soap (it must be Ivory!)

Tools

Scissors
Microwave

Step 2: Cut the Netting

First of all, wash your netting to get rid of all the garlic smell.
Make a large opening on the top of the netting by cutting it open with a pair of scissors.
Make sure the bottom of the garlic netting is sealed by tying a knot, or keeping the seal from the packaging.

Step 3: Fill It With Soap

Instead of throwing out your tiny, unusable soap leftovers, keep them and fill the garlic netting with these soap leftovers.
Alternatively, if you do not have any soap leftovers, you can wait, or just make your own, which is what I'd be showing you in the next step.

Step 4: [Optional] Microwave Ivory Soap

This step is completely safe to do in you microwave and will not damage it, assuming you follow the instructions properly below.

Microwave a block of ivory soap for about 20 - 30 seconds on medium heat or until the soap begins to puff up.
When it has puffed up remove it from the microwave carefully, since it is very hot.

Only ivory soap works for this step since it is the only brand that has a lot of air pockets stuck within the soap bar, which pop when microwaved. This is also the reason why Ivory soap floats on water. Any other soap brand would just melt and create a mess. Although, you'll be left with a soap smelling kitchen, which isn't too bad.
