Marshmallow & toothpick building 🏗age 4-8 🗼For this activity all you need are marshmallows and toothpicks. The boys loved building using these materials and spent over 20 minutes making their creations (they would’ve gone on for longer if I had let them). My 4 year old also got into this later and built his own structure. In fact, my whole dining room table is now filled with their creations but it has kept them occupied for hours. 😱The good news is they are slowly dismantling them and eating the marshmallows. 😂
