A British man created a full-size replica military tank from more than 5,000 egg cartons to raise money for a military charity. Stuart Murdoch said he used more than 6 gallons of glue, more than 10,000 nails, almost 4 gallons of paint, 262 square feet of steel and 5,013 staples to construct his Challenger 2 replica, The Mirror reported. The tank, which took Murdoch three weeks to complete, will be displayed in London as part of the festivities to commence a national egg and spoon race on March 4 to raise money for Help for Heroes, a charity that helps wounded servicemen and women returning from service.
