Guardian Online has 500 pairs of tickets - worth up to £23 - to give away for the UK's hottest showcase for science, technology and innovation - BBC Tomorrow's World Live event. The exhibition, held in association with the Department for Education and Employment (DfEE), takes place at Earls Court 2 between June 28-July 2 where a show within a show called Planet Internet With Yell.com will be unveiled.

Conceived as an interactive theme park, this is the first major national event to provide consumers with the opportunity to meet internet brands, learn internet facts and witness the web's full potential in one experience.

For example, visitors can see how an intelligent house can change their lives with Dreamcast games against friends in Japan, fridges ordering weekly groceries and temperature controls on the bath. Its digital TV and webcams enable the home environment to be controlled from afar, linking with a mobile phone or PDA to monitor the house. Cisco has brought all these technologies together in an interactive show for visitors to see for themselves.

Giveaways and prizes to be won at Planet Internet include a VW Beetle from Yell.com and a Ford KA3 from Totalise.net.

Other main features at the Tomorrow's World Live event include: Making Music, created by Roland UK with live sets from top bands; James Bond - 007's secret gadgets revealed, including the new BMW Z8; Gadget Shop - all the latest must-have gizmos; Directions - The UK's largest recruitment fair; and Inventor's Fair - a hotbed of 150 budding Dysons.

• To request a pair of free tickets, readers should call the ticket hotline on 0870 739 9333, quoting the reference TG101. The offer is open to the first 500 callers and subject to capacity restrictions.
