Basically, the light refraction gives the pencil a slight magnifying effect, which makes the angle appear bigger than it actually is, causing the pencil to look crooked.
Light travels through different materials, or mediums, at different speeds. This change in speed causes the light to bend, or refract, meaning that the part of the pencil that is in the water will appear shifted. However, if the pencil is taken out from the glass of water, its appearance will be back from its original shape.
