Looking for authentic science demonstrations that will awe and inspire your kids or grandchildren? This next video is just for you!
In "8 Water Tricks That'll Melt Your Mind," our pals at BuzzFeed reveal some very cool experiments that you can do at home to entertain both kids and adults alike. These awesome party tricks will be great to remember and most of them just use everyday items.
One of my favorites shown in the video is the pepper in water experiment. Just add a dose of pepper to a bowl of water, and when you put your finger in, the pepper doesn't move. But add a small dab of soap to your finger, dip it in, and watch what happens. The pepper suddenly shoots to the sides when soap touches the water.
So what causes this reaction? Soap is able to break down the surface tension of water, so as the soap moves into the water, and the surface tension changes, the pepper no longer floats on top. The water molecules still want to keep the surface tension going, so they pull away from the soap and carry the pepper along to the sides of the bowl. How cool is that?! Science is pretty awesome!
Watch the video to check out more awesome water hacks and tell us which one is your favorite.
