Lab Rats Challenge

Lab Rats Challenge is an Australian children's game show. The program began broadcasting on 4 August 2008 at 4pm on the Nine Network with hosts Drew Jarvis and Nicole Dixon. On 5 March 2012, the show moved to the Seven Network with Aleisha Rose replacing Dixon for the revived series. On 12 February 2013 at 10:15am, the show moved to ABC3 (now known as 'ABC ME'). The show has also been broadcast on Cartoon Network.
In contrast to other Australian children's game shows such as "Sharky's Friends", "A*mazing", and "Go Go Stop", which are filmed on a large set in front of a live studio audience, "Lab Rats Challenge" uses several smaller sets resembling an abandoned science laboratory as well as special effects sequences inserted in post-production. It is filmed in Brisbane's Channel 9 studio on Mount Coot-tha, Queensland.
Gameplay.
The challenges on the show are born from science experiments, such as guessing how many drops of water will fit on a twenty cent coin. Each episode's final challenge, The Labyrinth, features the children competitors racing through a series of physical and mental challenges. The 1st pair to make it through the labyrinth gets cheesed at the end. This is similar in style to the maze on early 1990s Australian kids game show "A*mazing" and 1990s American show "Legends of the Hidden Temple".
Rounds.
If there is a tie after What'll Happen If or the Rat Race, there is a tie breaker known as the Randomizer. Both teams are given a beaker of water along with two similar-looking containers of white powder. Only one would cause a chemical reaction when placed in the water. The team that wins the Rat Race gets to choose their powder first. Both teams pour their powder in the water and the one that has a chemical reaction wins. This tie breaker is completely based on chance.
Sounds boring, but there is one episode which has a sample Randomizer with white powder. More excitingly, there is one episode which has TWO Randomizers. It happened as both teams scored 15-15 and 65-65. This was in Series 1 Episode 20.
