A potion made from the essences in Roper Klacks' laboratory. When drunk, it makes April incredibly light for a short period of time, allowing her to jump much higher than normal. April says it would mean a guaranteed gold medal if she used it to enter the Olympic high jump.
This potion allows her to retrieve the Red Essence from the rafters of the laboratory. It also allows her to cross the gulf to the Alatien village of Tama'a after she uses the Wind Potion on the chasm, fooling Isaam, the Alatien on guard, into thinking she can fly.
Mixed in Roper Klacks' laboratory.
