In this episode of ‘The Gadget Show’ Jason and Suzi are set a challenge to design and build a gadget that will appeal to animals as well as humans. Who can produce the most innovative and ingenious gadget for pets? From a doggy treadmill to a flushing cat toilet, the duo endure animal mayhem as they test a selection of outlandish inventions in order to get some inspiration for their own builds. Despite being allergic to dogs, Jason opts for an automatic ball-launcher that takes the arm-work out of playing ‘fetch’ with a pooch. The idea is that the dog retrieves the ball and places it into the launcher. It is then hurled 30 metres and the process begins again. Because of her love of cats, Suzi decides to build a gadget for moggies. She always wonders where her cat goes when it disappears through the cat flap, so she develops a GPS tracking device and camera for cats to wear on a harness. Jason heads off to a dog show to see if his device has the audience begging for more, and Suzi tests her purr-fect invention with TV vet Scott Miller and his cat. Which invention will be a hit with the pets and their owners? Also this time, Ortis heads into the woods with ex-special forces hard man Mike Hawk to test the best pocket tools on the market. Jon, meanwhile, trawls through the top online photo-printing services available.

Jason and Ortis join forces to build an amazing power-tool racer. Following a thorough trouncing in 2008’s Silverline Power Tool Drag Race, they decide to enter again this year. This time, however, the boys really mean business! Firstly, Jason and Ortis assess the competition. They take a good look at the vehicles that have been victorious in previous years and research the technology behind their success. They also evaluate how their team came so hopelessly unstuck last year. Deciding that chainsaw-powered vehicles are the way to go, Jason and Ortis enlist the help of ace engineers Stewart Pilley and Matthew Ward. They then track down three Stihl 8.7bhp chainsaw engines, and set about constructing a cutting-edge chainsaw-powered go-kart that might place glory within their grasp... The team decides to source an old go-kart from a karting centre and strip it down. Ortis and Jason take out the engine, seat, steering wheel and existing wheels. The rear axle is also removed from the chassis and the gear ratio is calculated specifically for the chainsaws. Lastly, they paint the kart, add new wheels and fit protective plastic to the chassis. Race day finally arrives and Ortis and Jason head to Haynes Motor Museum in Somerset to see just what their go-kart is made of. Will Jason, Ortis and their chainsaw-powered go-kart blow the competition out of the water? Or will they be humiliated and defeated once again?

Suzi Perry visits the Rinspeed HQ in Germany to drive their latest creation, a hydrofoil car, while Ortis Deley goes for a spin in the new Sand-X dune bike in Dubai. Continuing the transport theme, Jon Bentley takes to the streets of Paris without the aid of a sat-nav to test the navigational tools of multimedia devices like phones, and Jason Bradbury straps a jet engine to the hoverboard he built in series five

Ortis Deley accompanies Jason Bradbury on a trip to the high-altitude glacial resort of Saas-Fee in Switzerland, where they test a range of skiing gear in an alpine race.
