Don't follow that picture. It creates mustard gas.

It smells weird and it leaves a gross residue on your dick.

Just use the sponge and rubber glove method.

Wouldn't try this mixture due to the unstable nature of it not forming a gel like substance easily, and the fact that it has subtle properties of a non-newtonian fluid leading to the substance bouncing back immediately and possibly fracturing your penis if enough force is applied. So don't go through with it.

if you stick your dick in that the chemicals will roast your cock

Can confirm there is literally nothing wrong with OP's pic. You just haven't tried it yet.
