NERF Blaster vs GIANT Paper Cup Pyramid. Roman and Max are testing an old Mega Mastodon Nerf Blaster. They already have one Mastodon, but they need two of them for their next giant Nerf project, which they are going to build in the next video. After a quick unboxing they are going to test their new Mastodon vs giant paper cup pyramid. It's a lot of fun blasting cup pyramids with a Nerf blaster.
