Foaming Bath Salts

Tweet

My earlier topic regarding the bath salts I made. I had an idea while walking about earlier. What if you could combine bubbles with salts? So I did a bit googling and found out bubble salts are a thing, but the ingredients are weird and complex. Do you think I could mix literal bubble bath in with the salts or would it just dissolve. Bath salts are generally dry but surely I could pull it off? Just an idea I'm having and want to hear peoples thoughts.
