Propolis season. Normally, it is dark brown in color, but it can be found in green, red, black, and white hues, depending on the sources of resin found in the particular hive area. Honey bees are opportunists, gathering what they need from available sources, and detailed analyses show that the chemical composition of propolis varies considerably from region to region, along with the vegetation. In northern temperate climates, for example, bees collect resins from trees, such as poplars and conifers (the biological role of resin in trees is to seal wounds and defend against bacteria, fungi and insects). "Typical" northern temperate
Speed glue Butterfly's Bryce FX, Joola's Samba, will absorb the glue more readily and therefore have a bigger dome when they expand, leading to a greater effect, with harder sponges e.g. most Chinese rubbers, Butterfly's Bryce Hard, expanding less leading to a slightly lesser effect. In gameplay terms, speed glue has some disadvantages. Due to the increased sponge thickness, speed does increase, but as mentioned before usually control decreases as speed increases. Also, after several regluings speed glue begins to build up on the racket, increasing the weight of the paddle. The nature of table tennis blades are so sensitive, that a
