These work great for doing anything needed with liquid watercolors, we've used them in water guns to spray at canvas, mix with bubbles to do bubble art, and also mixed with baking soda and vinegar to do chemical reactions with our art. The color is vibrant, and shows up well both on canvas and watercolor paper. We've purchased twice and have been happy with the product both times.
