Can you help this week's hero save the city from a deadly virus? If you think you can, you could win the original drawing of Staz's artwork on this page. All you have to do is solve the challenge below, and send it in to us.

The Evil Nemesis has hidden the antidote to a deadly virus in a glass jar with a metal lid. Only The Element can save the city from the ravages of the virus by recovering the antidote. Having tracked down the Evil Nemesis to her bodacious boudoir, The Element soon finds the jar and attempts to open it. But even with her super-strength the lid is simply too tight to budge.

The Element doesn't want to risk breaking the jar in case it damages the antidote. Time is running out, what can she do? Can you, as her faithful sidekick, help her open the jar? With one hand resting on your trusty travel hairdryer in its hip holster, you know you need to think fast.

This competition is now closed. The winner was Scott Burrows.

With not a moment to lose, hand our hero your hairdryer and tell her to heat up the lid of the jar with it. Because it's a better conductor of heat, the metal lid will heat up quicker than the glass jar, causing it to expand faster and so loosen. Another city saved!
