15 September, 2026Chestnut Laundry Detergent: The Autumn Experiment That Will Amaze Kids
From Horse Chestnuts to Natural Laundry Detergent
What looks like an ordinary autumn treasure can turn into a little science experiment. 🍂
In this hands-on activity, children discover that horse chestnuts contain natural saponins - substances that create a soapy effect and can be used to make a simple laundry detergent. From collecting and sorting the chestnuts to shaking, observing and testing the result on a stained cloth, the experiment combines nature, curiosity and learning in a fun and practical way.
A great autumn activity for daycare groups and curious little explorers, with simple materials and plenty of opportunities to discover how nature can surprise us.
Suitable from age 3 · Collecting from age 2 with adult supervision
