LEVEL 92: HELP!

I cannot finish level 92. To refresh your memory, the level has 2 bombs, set at 15 seconds, which are below several layers of 'sand'. I have tried and tired, but cannot even come close to getting anything to work in being able to pop them before they blow up. I've searched the internet to no avail for answers. If anyone can help, please do so! THANKS IN ADVANCE!

When you start a level with timed bombs, hit "menu" (top right), then options and relaxed mode. There you can turn the bomb of (and the timer and the oil, if you want to). Then OK, OK and resume. The bombs are still there, but they are not timed any more.
These options you can switch on and off, you can also do it from the Main Menu.

OMG Thank you, hraili! I was going nuts with this one. I appreciate the help!
