You can make interesting bottle dishes, planters and other cool things.

Some of the materials/tools used:

For your own safety:

Make sure to use a cordless rotary tool, not one with the cable.

First I marked a cutting line with a copper adhesive tape.

You can use a permanent marker or don't mark the bottle at all.

Some bottles will have a line on the sides.

I prefer to use the tape as it's easier to see it.

You will want to lubricate and cool the bottle with water.

Since I don't have a workshop, I had to do it in the kitchen.

I used a suction vise to hold the bottle.

It's perfect as you can attach it to the sink.

Take a cordless rotary tool with a diamond cutting disk.

Start cutting the bottle while pouring/running the water on the spot you're cutting.

It can get wet, so you might want to cover things near your sink with the plastic.

First I cut one side of the bottle, then the bottom and then the other side.

Most likely the cut will not be perfect and you will want to sand it.

I used silicon carbide powder.

You mix it with water and sand the bottle on top of a piece of glass.

You can also use a wet sandpaper or a rotary tool with a sanding bit.

In one of the bottles I planted a wheat grass and other I used as a dish.
