Roots and Wings Co have created a detailed tutorial that gives all the steps you need on how to make your own soap bars that look like bricks of Lego.

The mold that created the bricks was made of urethane and was shaped around actual Lego bricks. By attaching the real Lego bricks to a surface and building up surrounding walls it allows the liquid urethane to be poured and left to set. Once the mold is created it allows for soap to be poured and again left to set creating some colourful Lego soap bricks.

The details captured by the urethane mold actually recreates the word Lego on the top of each dot. Full details of the tutorial can be found over here.

Home-made Lego Soap Bricks are amazing
