Here's a cute soap bar I made last year. I remember I spent a few hours handcrafting my very own TARDIS, but made out of soap, not wood.
I bought a large block of $16 soap for 50% off, plus blue colouring, and a rectangular mold, which also happened to be blue.
I melted the soap in the microwave, then poured it into the mold.
I let it sit for about an hour then popped it out.
I did one more pouring to a shallow depth and let set.
When I was ready to assemble, I grabbed the toothpicks and sliced, diced and chopped until I had a reasonable assemblage of a time machine.
I melted a bit more soap, added red and cut out a light for the top.
Now that my TARDIS is in the past, I’m not certain I would do the assembly method again. Perhaps I will make my own TARDIS mold and pour directly into it.
See the photo above of my wonderful TARDIS! What ever happened to it? Turns out I needed soap in the bathroom one day so I cut it down into blocks and used it all up. In the future I'll be on the lookout for an actual TARDIS mold that will contain more detail.
