Would you believe me if I told you that you can punch a hole in a water bottle and it won't leak? No, of course not. We all know some water will flow out. But will all of the water flow out? That's the question I want you to ask yourself as you do this experiment. Materials:
Extension: Find out if the same amount of water flows out whether you have a hole near the top or a hole near the bottom (you can use the same bottle if you can make a good seal - using duct tape - over the hole that you are not currently testing). Extension 2: Create 2 holes in your bottle - one an inch or so from the top and one nearer the bottom. Put duct tape over both holes. Fill the bottle with water and put the lid on. Open the lid a little so air can get in. When you're ready, remove one of the pieces of duct tape and then watch the shape of the arc as the water leaves the hole. You can also notice how far from the bottle the water from the hole went. Then reset the experiment and do it again opening the other hole. Is there a difference? Parent Tip: This activity involves water. Either do this in the sink, on a tray or outside. Have students make a guess (hypothesis) about what they think will happen before they do it. How To Links & Explanation: Here is the link to the instructions, video, explanation, and extensions. Thanks to the Science Buddies for this activity.
