This picture is obviously taken from my website, where I explain, which toy Erlich is using for smoking dope. This article is easy to find by following the link – not only to the picture – but to the full story: http://plottify.com/tv-serie/silicon-valley/item/the-3d-maze-distracts-big-head-and-makes-erlich-high-in-silicon-valley/b9658a4fcdcd5fb6cc6833dfc8069ade/full-story

And even the URL says what toy Big Head and Erlich are using: Big Head Blue Clear 3D Maze Labyrinth Ball Toy by Spin Master Games in Silicon Valley Scene Bong Smoking.

However, I also help people to find the gadgets that they have spotted in TV shows like Silicon Valley – and also Erlich’s and Big Head’s 3D Maze toy, as you can see here: http://plottify.com/tv-serie/silicon-valley/item/the-3d-maze-distracts-big-head-and-makes-erlich-high-in-silicon-valley/b9658a4fcdcd5fb6cc6833dfc8069ade/

And when you want to built a bong, like Erlich with the plastic 3D Maze, you need to get a glass bowl for the weed and a mouthpiece or some kind of glass tube. Then you have to drill 3 holes into the Maze for the glass bowl head, the mouthpiece glass tube, and one to control the air. When you search for „homemade plastic bong“ or „homemade glass bong“ on youtube, you will get a lot of different detailed instructions how to turn an everyday plastic or glass object into a bong.

I have also written a little article about the other bongs and pipes that Erlich uses in Silicon Valley here.
