Brazil-nut Effect (BNE) experiment in (real) two-dimension is conducted. Container, bed particles, and intruder are made from the same material, i.e. 2 mm thickness acrylic plate. Dimensionless acceleration r and vibration frequency f are in the range of 2-4 and 13-17 Hz, respectively. It is observed that rise time Trise decreases with the increase of Γ similar to reported by others, but there is a range of f and Γ, where Trise increases with the increase of Γ due to occurrence of Leidenfrost effect, which reduces convection flow of granular particles.
