Porch pirates beware: Glitter bomb 2.0 has Kevin McAllister’s OK

Not all heroes wear capes. Some accessorize with glitter, fart spray and the element of surprise.

You may remember Mark Rober, the former NASA engineer who rose to YouTube fame last year after a $5 package was stolen from his doorstep. His mission: to exact a little justice by leaving booby-trapped boxes outside homes — making it very, very clear to any would-be thief that they’d messed with the wrong porch.

On Sunday, Rober unveiled a souped-up version of his creation, one he spent 11 months engineering with the same precision he put into the Curiosity Mars rover. A YouTube video viewed more than 7.9 million times breaks down how Rober’s “glitter bomb” works, and includes bonus footage of real-life thieves who meet their smelly fates.

This time around, Rober scored a coveted endorsement: Macaulay Culkin — the “Home Alone” actor and muse behind the glitter bomb itself. He makes a cameo in the video, and even takes the fart spray for a test run to ensure optimal ... effect.

Rober is a YouTube sensation, and spends much of his time making videos of quirky science experiments. But his porch protection program comes as holiday packages are circling the country in droves. Between Thanksgiving and Jan. 1, the U.S. Postal Service expects to ship more than 800 million packages.

The new and improved glitter bomb includes a circuit board and four phones that record the sting from all sides and upload footage to the cloud.

Robbers will be most stunned by the surge of glitter and a rush of reengineered fart spray.
