This is why I am a teacher. What can 5th grade boys do on an indoor recess with 1/2 a plastic water bottle, 3 straws, tape, and string? A zip line that’s what! Today I subbed in a 5th grade classroom, where a group of boys made this outstanding zip line. They attached it to opposite ends of the classroom and then let it rip, with lego men in it, of course. So cool!!!! They be-stilled a teacher’s heart by doing time trials at various heights. Awesome!!!!!
