In a world first, Sony Ericsson has launched an exciting interactive piece of activity which will enable consumers to pump up space hoppers using Twitter.

Consumers will be directed to a website www.sonyericsson.com/hopperinvasion where they will be able to take part.

The site hosts a live video feed of a (secret) warehouse in which deflated hoppers are arranged on a grid waiting to be pumped up.

Anyone on the site or on Twitter can tweet #pumpt and see a hopper being inflated. At the same time Sony Ericsson are asking people to tell them what they would do with the space hoppers, the best suggestion received will be made real, filmed and posted online.

The site is part of the "Spark Something" campaign designed to support the Satio™ and Aino™ handsets.

No space hoppers were harmed in the making of this campaign.

Sony Ericsson launched the third phase today of its ground breaking "Spark Something" campaign to support the Satio™ and Aino™ handsets. The campaign, which has already created the world's first online flashmob (a screen invasion on several Yahoo homepages around the world over the last few weeks,) will now see the world's first automated use of Twitter to create real life events.

As of today, users who tweet #pumpt will be able to watch as their tweet prompts the real life inflation of a space hopper. They will also be able to suggest a possible use for the inflated space hopper and the best of these suggestions will be re-created and filmed.

Already the campaign has seen more than 180,000 virtual space hoppers created by users engaging with the campaign site and a YouTube™ video of the TVC has generated more than 800,000 views. So far more than 1,200 people have taken part in six online screen invasions of sites across the globe, using a browser cookie to link their personally created space hopper to their current location.

On each screen invasion a countdown alerted users to the imminence of the flash mob. As it reached zero a display advert used the browser cookie to work out which registered users were present and allowed their personal space hoppers to break out of the advert.
