3D glasses for a smartphone do-it-yourself

Of course you can buy 3D glasses, but it will be much more interesting to make them. The most accessible material for this craft will be cardboard, of course, if there is not something better. Probably the most difficult will be the manufacture of lenses, a plastic bottle, hot melt adhesive and water are suitable for this.

When the glasses are ready, you need to find videos or games that support 3D glasses and try a new craft.
