Coloured rice sensory play kits made in a home kitchen, Brazil

The idea

Sensory play kits let small children scoop, pour and sort coloured material instead of watching a screen. The simplest kit is rice dyed with food colouring, packed in a bag or tub. Parents buy it for calm, screen-free time at home, and kindergartens can buy it for activity tables.

The idea is seen in Brazil and was made popular by Juliana Blois, a mother who dyed pantry rice during the pandemic to keep her toddler busy while a newborn slept. The girl played for more than an hour. Blois listed a few bags on Facebook Marketplace, and other parents asked for more, such as homemade play dough kits. She then opened an Etsy shop. According to her account, she reached about US$6,300 in sales in a single month around late 2021 and has sold more than 10,000 sensory mixes. In 2023 she narrowed her range to mixes and fillers only, which she says helped growth. She started on her kitchen table.

Who it fits

This suits a parent, a carer or a crafty person with a kitchen, a few hours a week and a phone for photos and short videos. It works beside a job or childcare, since batches can be made in an evening and dried overnight. It would work in any country where families buy educational toys and where rice or another cheap dry base is easy to find.

Costs and revenue

Expect roughly $100–$500 to start: rice, food colouring, resealable bags or tubs, labels, small scoops and a few cheap themed add-ons. These are editorial estimates, not figures from the source.

Price by the kit or by the colour theme, for example a rainbow bag or a seasonal mix. Ingredient cost per kit is tiny, so most of your margin goes on packaging, platform fees and postage. A part-time seller can typically expect around $200–$1,500 a month, and a well-run online shop with strong content may go higher. Blois's best reported month is an exception, not a promise.

Risks and pitfalls

• Safety: Sensory play must be supervised and only for children who no longer put objects in their mouths. Print this clearly on every label.
• Food waste criticism: Some people object to using rice for play. Offer a non-food base option and explain your choice openly.
• Mould and damp: Dry the rice fully and store it sealed so it does not spoil on the way to customers.
• Crowded market: Many people can copy the recipe. Stand out with colour palettes, themes and clear tutorials.
• Too many products: Blois says a wide range pulled her attention away. Keep the line short and focused.
