Clock stops, replacements. Two men in Lego heads watch on. Doesn't seem a great idea in these heat. Just over three minutes to go.

What an amazing athlete Dan Norton is. Not only is he fast, his footwork is fantastic. That was sevens rugby at its best.
GB 7-5 South Africa
Oh yes! Dan Norton, on the far wing, dances past the tackle like Fred Astaire. After that, he shows the South Africa defence a clean pair of heels to score under the posts. Kick added. Britain lead.
GB 0-5 South Africa
Rugby back under way. Seven minutes for GB to win a medal...
Men's C2
Also, David Florence and Richard Hounslow have been speaking to BBC Two after their canoe slalom silver.
"I was a bit disappointed from the C1. I really wanted to go out there and enjoy it," Florence said.
"Rich is so solid on race days. You know nothing is going to faze him. It helped having him there, it picked me up a bit."
"t has been a hard eight years, we've worked really hard and to come out with a medal at the Olympics is fantastic," Hounslow added.
"It is maybe a little bit bittersweet, coming so close to gold, but we’re happy."
At the break, there's time to remind you of Joshua Buatsi's impressive performance earlier to move into the quarter-finals of the men's light heavy -81kg category. You can watch it here...
HT: GB 0-5 South Africa
Half-time. GB, with the disadvantage of that breeze, only five behind at the interval. Very much still in it.
GB 0-5 South Africa
My word, South Africa are putting some tackles in. Seconds ticking down in this half...
GB 0-5 South Africa
GB, playing into a strong wind, under more pressure. They'd probably take only being five behind at half-time...

You have to say GB defended very well from a turonover but the ball just comes out and it's excellent play from Rosko Specman to keep it alive and allow Kyle Brown to score.
GB 0-5 South Africa
Great Britain are struggling to make ground, pegged back in their own territory. James Rodwell does run through, but is taken down...
GB 0-5 South Africa
Great Britain are behind. The ball squirts free, Kyle Brown pounces and runs in at the corner. A tricky kick is missed.
GB 0-0 South Africa
GB get us under way. 14 minutes between them and a medal...
South Africa lost in the pool stage to Australia, but then beat the Aussies in the semis. GB are sporting the red they wore in their dramatic last-eight win over Argentina last night.
Those sevens rugby matches are later this evening, with a third-fourth play-off deciding who takes bronze. GB, with four wins from four so far, are about to take the field and will be backed by some strong travelling support.
The action is coming thick and fast. Remember, Fiona Pennie goes in the K1 final but, before that, Great Britain have the chance to secure a medal in the rugby sevens. Their semi-final against South Africa kicks-off at 19:00, with the winners guaranteed at least silver. Fiji await in the final.
There's better news for James Guy, though, who has won his 100m butterfly heat. You can watch that right here...
Fognini 1-6 6-2 1-0 Murray
While Florence and Hounslow were winning GB's 14th medal of the Games, one strong medal prospect has had a little bit of a wobble.
Andy Murray, who had his pipe and slippers out before that canoeing final, lost the second set to Fabio Fognini and is now all-square in the decider.
The defending champ is looking for a place in the last eight.
Loved the drama of the canoe slalom? The British Isles are a fantastic place to learn, and there are hundreds of clubs you can go to to give it a try.

We have divers at the canoe slalom but for all the right reasons as Slovakia go wild.
The Skantar cousins edge out Great Britain so it's groundhog day for David Florence and Richard Hounslow as they make it two silver medals in this event in two Games.
As the Germans were nudged out of the places thanks to a poor second half of the run, a cluster of fans sporting the country's flag just seemed to disappear from the stands. They expected more from the world champion pairing.
