You will need three pieces of tealight candle.

You will also need a glass tealight candle holder.

Light two of the candles to melt it and remove it from the container.

Once melted remove the candle.

You will need two of this container.

For the first one cut a rectangular shape at the middle part of the bottom. This open space is where you will put the part of the styrene that you will bend

On the second container cut the bottom part and drill holes on the sides.

These holes will help to allow air to flow inside so that the candle will not get diffused.

Now it's time to put together the materials. First put the container with holes.

Then put the other container at the top facing down.

put the part of the styrene in the middle and let it stay for 3-5 seconds. It will soften the styrene due to the heat seeping out of the open area but not hot enough to melt it all through out like heating it directly.

bend the styrene to the angle you need and hold it in place until the styrene hardened again.
Note that once you heated polystyrene plastic, it will hardened it and bending it after you heated it will cause it to break.
