Directions
Take frozen water cups out of the freezer. Place cups onto a tray. Invite your child to scoop approximately 1/4 cup of baking soda on top of the frozen water. Place the pipette into vinegar, squeeze the top, release so the vinegar gets sucked up into the pipette. Then squeeze the pipette over the vinegar and observe what happens.
