Innovative Aerator Tells You How Well Compost is Cooking

What a hot idea! Not only does this ingenious device aerate your compost pile, it takes the compost's temperature so you know whether it's active. The thermal chromatic purple wing turns pink when material is hot enough to start composting (about 94º F). Both wings are spring-loaded; they fold back to plunge deep into the pile, then open to create airholes that allow compost to breathe.

• Dual-purpose tool aerates compost and indicates temperature.
• When wing turns pink you know compost is cooking.
• Leave in compost pile for an instant read next time.
