Hispania not out of their depth
The Spanish team likes to broaden its drivers' horizons away from the insular world of F1, and so after jet-skiing in Malaysia, firefighting in Monaco and hospital visits in Istanbul came dolphin training in Valencia.
Would a few lessons from the Oceanografic - Europe's largest aquarium - help the F1 minnows cope with the sport's big fish?
"We enjoy ourselves a little bit away from the track," said Senna, who was a natural at coaxing dolphins Venus and Virkin into jumps and spins after some coaching tips from the trainers.
"The dolphins are very curious animals, it's amazing. Did you see that? That one did like five back flips!"
Chandhok was less keen on getting close to the water's edge.
"He's scared of water in general," teased Senna.
"Well that's not true," Chandhok retorted. "But I am a bit afraid of the dolphins. Their mouths are massive.
"I saw Jaws too many times as a child so I must still be traumatised. Take me to a dog park and I'll be OK."
Chandhok and Senna are still learning how to mix with F1's big fish as they approach the halfway point in their rookie seasons.
In Montreal, Chandhok's Hispania delayed Fernando Alonso's Ferrari to such an extent that the Spaniard lost second place to Jenson Button's McLaren and he had earlier lost the chance to take the lead from Button's team-mate Lewis Hamilton when he was delayed by Jarno Trulli's Lotus. Alonso said afterwards that traffic cost him a chance of victory.
But Chandhok believes dealing with slower cars has always been part of racing in F1 and it is something all 24 cars in the field will have to get used to.
"Drivers have been blocked or cost time by slower cars for decades in F1," argued Chandhok.
"When Ayrton Senna used to drive he was a specialist at beating people through traffic.
"I wasn't in the way or trying to intentionally block Alonso. I was trying to get out of the way.
"To be fair, drivers like Fernando haven't ever really complained about the new teams.
"I know his team have been quite vocal about it but Fernando's driven a Minardi so he knows what it's like to be five or six seconds off the pace and he's always been very supportive."
Senna added: "When you are fighting for position with faster cars you do try to block them but it doesn't last for too long unfortunately."
The priority for the Hispania drivers in the second half of the second is to close the gap on rookie rivals Lotus - ahead by 1.247 seconds in Montreal - and Virgin Racing.
The team have already made solid progress since turning up for the opening race in Bahrain without turning a wheel in pre-season testing.
Hispania were almost 10 seconds off the pace in Bahrain but six races later in Istanbul Senna out-qualified another car - Lucas di Grassi's Virgin - on merit for the first time and in Montreal Senna was just 0.543 secs adrift of Timo Glock's leading Virgin.
"We want to be the best of the new teams by Abu Dhabi," added Chandhok.
"It may not happen in terms of the championship position because we would have lost half a season but if we can compete against Lotus, even if it's the last third of the season, it puts us and the team into a more credible position going into 2011.
"We have made progress. We've had more reliability than the other two news teams this year but in terms of performance, it is stalemate."
