Kids build a solar-powered moisture sensor to tell them when their plant needs water.
MAKE A MOISTURE SENSOR
Use plaster and electronic components to make a sensor. Just twist wires together to make an awesome circuit.
POWER YOUR SENSOR WITH SOLAR ENERGY
Use a solar panel to keep your sensor running – no batteries required!
KEEP ALL YOUR PLANTS HAPPY!
From cacti to bonsai, the Thirsty Plant kit will work with any type of plant.
