Science With Kids

Super Bubbles: in a large bucket, gently mix together 8 liters of warm water with 1/2 cup liquid dishwashing detergent (dawn works best, avoid using a soap with antibacterial properties). Use a bubble wand to create your floaters. Put on clean gloves and bounce the bubbles off your hands! Then try to bounce them off your clothes, they will pop. If the clothes are dirty the oil and dirt particles will break down the soap's film and the bubbles will pop

Bursting Bags: Add 1 TB baking soda to a quart size zipper lock plastic bag. Add 1/2 cup vinegar to a snack-size zipper lock plastic bag and seal it. Place the small bag in the large one, seal the large bag, and put on your safty glasses (or sun glasses). Punch the vinegar bag inside the baking soda bag to break it open and shake the bags to mix the substances. Watch the bag puff up and then pop! When you mix vinegar and baking soda a gas is produced (carbon dioxide)

Fireworks Milk: Cover the bottom of a dinner plate with 2% milk. Allow the milk to settle. Add 1 drop each of red, blue, yellow, and green food coloring to the milk. Place a drop of liquid dish soap on the end of a cotton swab. Touch the milk with the soapy end of the swab and hold it there for 10 - 15 seconds. It will look like fireworks! Milk is made up mostly of water but it also contains vitamins, minerals, proteins, and fat. When you add soap, the weak chemical bonds are altered and the molecules of protein and fat bend, twist, roll and contort in all directions
