Projectile pumpkins take over the sky as PUNKIN CHUNKIN returns to Science Channel with a three hour simulcast with Discovery Channel – that's more primetime gourd-chunkin hours than ever before! Punkin Chunkin is the epic gathering of unconventional engineering teams and builders who compete using a variety of technologies - air cannons, catapults, trebuchets and other homemade contraptions - to see who can propel a pumpkin the farthest. This signature Science Channel television event celebrates the science and engineering skills of all those who compete, as well as their creativity, ingenuity, teamwork, and passion. PUNKIN CHUNKINreturns in all its glory after a two-year absence as a simulcast on Science Channel and Discovery Channel Saturday, Nov. 26 at 8PM.
