Mark features some of his biggest, craziest and most visual experiments ever, and highlights his relationship with a young man who motivated his second world record attempt.

Mark helps viewers dive into three pools; one is filled with 25 million Orbeez, one is filled with liquid sand and one is filled with jello; he unveils a never-before-seen, top-secret blaster.

Mark takes viewers from the original story through current iteration, culminating in a never-before-seen glitter bomb that is too dangerous to be unleashed on the public.

In his quest to understand terminal velocity, Mark carefully studies some furry friends before jumping out of an airplane to become a flying human squirrel.

The world’s largest Super Soaker, the world’s largest Nerf blaster, and a snowball machine gun are among Mark’s most ridiculously scaled-up creations.

Mark gets sporty in a field-goal kicking contest with his mechanical creation, shows off a rocket-powered golf club and perfects the art of rock skipping.
