My kids watch a lot of youtube channels, many of them science related and its not uncommon for them to bring me a video and ask if we can do the experiment/demo shown on the video.  Well, now that they are both teens it appears that I’m not needed any more. My youngest (13) asked me for a bulldog clip and I saw him wandering around the house with a ziplock of water… hmmm.  A few minutes later he proudly showed me his ziplock full water and pencils and toothpicks.  Cool!IMG_3458.jpg
