Milk Machine
This machine makes you push a button and you get a cup of milk. You can make an Oreo machine to go with this.
Supplies
Cardboard, plastic water bottle, air motor, 9v battery. And of course milk!
Making the Circuit.
Using the air motor connect the button to the battery and the air motor. Push the button and the air motor will shake.
Making the Base of the Milk Machine
Make a rectangle of cardboard and cut out a tiny hole for the tube. Make a place for the battery and the button. Using the bottle poke a hole in the top. Put two tubes into the holes and attach one tone to the air motor. Poke the other tube into the hole you made on the milk base. Fill the bottle with milk and screw the cap on. Turn the machine on and the milk will pour out.
