Turn a used toilet paper roll into a fantastical garden of colorful salt crystals! Creator Jim, AKA HvySteel, is part artist, part scientist. His HowTo brings back great memories of our youth.
To get such ornate sculptures, proper chemical reactions must take place. 'The crystals are formed by salt molecules joining together as the liquid evaporates into the air. The ammonia helps to speed the rate of evaporation.' ¹
This garden blooms indefinitely. Add new colors for a layering effect. Add new growth platforms like sponges, charcoal or strings to grow a more complex structure.
