UPDATED WITH VIDEO: Tesco worker’s David Blaine-style glass box challenge at Broadfields store

A plucky supermarket worker will live inside a glass box for 50 hours during a David Blaine-style challenge outside Tesco Broadfields.

Callum Mills, 18, began the challenge this morning to raise awareness of autism.

Shoppers can monitor his progress throughout the challenge. The former Aylesbury Vale Academy pupil will leave the box at midday on Friday.

Callum, who has worked at Tesco Broadfields since 2014, said: “I know parents of autistic children have told the charity that the glass box is a really powerful metaphor for the condition.

“Being stared at from all directions, whilst being isolated and finding it difficult to communicate, is often how those living with autism feel.’’

Andy Bailey from the Cauldwell Children charity which will benefit from the challenge, said: “Callum is a popular chap with a great sense of humour, which I think will prove vital once the challenge starts.

“There is not much space inside the box, and I imagine he will experience vulnerability and frustration as the hours pass by. Also, mobile phones and gadgets are banned, so he will be relying on the public to get him through the days and nights.”

The challenge ties in with the 8th World Autism Day, held every year on April 2, when charities and families unite to celebrate autism and raise further awareness of the condition.

Caudwell Children will be supporting Callum through his 50 hour challenge, with staff and volunteers on hand to share with the public the support provided through the Autistic Children’s Therapies programme, which provides a series of therapies, education, dietry and nutritional interventions.

If he needs to Callum can leave the box for five minutes every two hours, so shoppers will not have to witness some of the more private moments of the 50 hours.
