The Sandstorm in a Bottle is an accessory that was added in the 1.2 update. It can be found in Pyramid treasure rooms and, when equipped, it allows the player to do a double jump of greater height than that of the Cloud in a Bottle - in fact, it could be said to be functionally similar to the Rocket Boots, only shorter-lived as the jump length can be controlled. However, it cannot be reinstated after it has been interrupted.
Of the three jump boost bottles, Sandstorm has the greatest length, allowing the player to jump a maximum distance of 20.5 blocks high. Blizzard in a bottle has a noticeably shorter height distance than this and Cloud in a Bottle can only provide an extra jump without any additional distance.
When using the Sandstorm in a Bottle the player seems to be spinning around very quickly.
