Fizzy Moon Sand
Have a science-loving child at home? This fizzy moon sand is a fun blend of sensory play and science that will only require a few ingredients and a couple minutes of your time!
Servings: 1 sensory bin
Ingredients
- 1 cup all-purpose flour
- 1 cup baking soda
- oil-based candy coloring optional, as needed
- ¼ cup oil (e.g. vegetable oil, melted coconut oil, mineral oil)
- vinegar as needed
- 1 plastic dropper
Instructions
- If desired, use a toothpick or popsicle stick to stir several globs of candy coloring into the oil. (To make white moon sand, skip this step.)
- Pour the flour and baking soda into a medium bowl, and stir them together with a spoon.
- Pour the colored oil into the dry ingredients and stir with a spoon to combine. Once you’ve gotten as far as you can with the spoon, continue with your hands, stopping only once the color has fully spread throughout. Play with the sand by molding it with your hands or adding vinegar with a dropper to make it fizz.

Notes
1. Making it taste-safe: Use edible cooking oil, like vegetable or coconut, and heat treat the flour by spreading it on a baking sheet and baking it at 350˚F for 5 minutes. The sand should only be consumed in small quantities due to the salt content in the baking soda.
2. Choosing your coloring: Regular liquid food coloring is water-based and won’t mix with the oil. Use oil-based candy coloring or add a very small amount of powdered coloring to the dry ingredients (but don't use too much to avoid staining hands).
3. Storage instructions: Dry moon sand can be stored in an air-tight container or zip-top bag and store at room temperature for up to 4 weeks. Once vinegar has been added, wet moon sand will need to be discarded after play.
4. Fun variations: Switch things up by choosing fun themes and accessories, adding glitter, or combining two colors to create new shades.
5. Limiting the mess: Cover your work surface, keep your moon sand contained inside a bin during play, and have some water handy to wash your child's hands. You may also want to consider taking the sand outdoors (weather permitting) or playing with it inside a bathtub or pop-up kiddy pool.
6. Helpful tips:
- Use enough coloring: The color will lighten significantly once the dry ingredients have been mixed in, so use more coloring than you think you need.
- Follow a 4:4:1 ratio: Make smaller or larger batches by sticking to a 4:4:1 ratio of flour to baking soda to oil.
- Make it last for longer: To make it last as long as possible, start by playing with the dry sand and only add vinegar once you're done. You can also set aside some sand and only add the vinegar to that portion while keeping the remainder dry.
