#180blog Today we had a water balloon fight for science! Topic: impulse. Question: hire much force is required to break a water balloon? We used slo-mo video to get impact time from an app called Ubersense. The kid in the video has his phone, filming from ground level, under a plastic bin to keep phone dry.

Fun fact: this post was created automatically using a recipe I programmed on IFTTT. It grabs all my Instagrams hashtagged with #180blog and auto-publishes them.
