Propolis while also collecting water and tree resin necessary for the production of propolis. The chemical composition and nature of propolis depend on environmental conditions and harvested resources. For centuries, beekeepers assumed that bees sealed the beehive with propolis to protect the colony from the elements, such as rain and cold winter drafts. However, 20th century research revealed that bees not only survive, but also thrive, with increased ventilation during the winter months throughout most temperate regions of the world. Propolis properties may include: The composition of propolis varies from hive to hive, from district to district, and from season to
Speed glue few extra grams may cause the player to not perform as well. The more the glue builds up on the rubber, the more glue must be applied on the next application to achieve the same effect. After 5-10 layers of glue, some players peel the old glue off to reduce the weight of the sponge, and to reduce the amount of glue needed to obtain the optimum effect. Another disadvantage is that the increased tension on the sponge from the glue will cause the rubber to wear out faster than usual. In order to prolong the life of the rubber,
