Spin Block

From the Super Mario Wiki

Spin Blocks are blocks (actually platforms) that are found in New Super Mario Bros. When stepped on, Mario or Luigi will start spinning. Upon jumping, the character will fly high into the air, then glide back down slowly, allowing the brothers to travel longer distances. Pressing down while in the air caused Mario and Luigi to perform a downward drill-like move, with the ability to destroy Brick Blocks.
