Gak is a Premium Toy

Gak

Nickelodeon/Mattel's most popular compound; the idea was taken from the Nickelodeon show Double Dare and Wham-O's Super Stuff from the mid-1960s. The original edition was manufactured in 1992, and then re-issued in 1994 for the Nickelodeon Deluxe Gift Set which included one canister of Nickelodeon Gak and two canisters of Nickelodeon Floam. It was marketed on the fact that, unlike most of the compounds, it made a "fart" noise when squeezed into its clear, star-shaped container. Gak (among other varieties and accessories) returned to store shelves with modern-day Nickelodeon branding in 2012 and 2017; both 2010s incarnations were produced by NSI International.

The name "gak" had previously been used by Marc Summers and the Double Dare crew to refer to slime used on the show. The name had originated as a street term for heroin. This was a source of amusement behind the scenes of Double Dare when Nickelodeon used the term for the toy Gak, unaware of its origin in drug culture.

Gak-in-the-Dark

Nickelodeon/Mattel's second kind of Gak that glowed in the dark after exposure to light. This variety was manufactured in 1994 and advertised in 1996 alongside the Make-Your-Own Gak Lab. The second and third incarnations were manufactured by NSI International in 2012 and 2017.

Solar Gak

Nickelodeon/Mattel's third kind of Gak that changed color when exposed to sunlight. Colors varied from Blue to Light Blue, Green to Light Green, and Purple to Lighter Purple. This variety was manufactured in 1995. A second incarnation was slated to be resold by NSI International in 2013, with colors varying from Pink to Purple and Light Blue to Blue.

Smell My Gak

Nickelodeon/Mattel's fourth version of Gak that was scented. It was manufactured in 1996 with scents including Pickles, Flowers, Vanilla ice cream, Buttered Popcorn, Sunscreen, Hot Dog, Pepperoni Pizza, and Baby Powder. The cover of the original toy featured child actor Sean Martinez. This variety was resold by NSI International in 2013 with scents including Green Apple, Vanilla, Flowers, Bacon, Garbage, and Stinky Shoe.

Gak Activity Sets

Gak Pak

Three different color Gaks in one big container.

Gak Vac

A toy vacuum that sucks Gak up and spits it out. Four monster figures (called "Gakoids" in the 2012 re-release) are included. The toy was re-released with a new design by NSI International in 2012.

Gak's Alive

Gak's Alive was a dark black-colored Gak that was filled with magnetic particles or fine iron filings. The activity set also included a "magic wand" with a magnet on the end that could be used to entice the Gak to creep or move on its own.
