Sensory Light Table: Valentine Sensory Bin

I've started working on color recognition with our toddler. Red was the color all last week and I created a Valentine sensory bin for him to play in. He LOVED it! He played with it for a good 25 minutes or so. This is a record for him. Usually his attention span lasts about five minutes and then he moves on.

Included in bin:
--Red colored epsom bath salt (I found 2 lb. cartons at Dollar Tree--dyed with about 12 drops of food coloring)
--'X' and 'O' plastic gems, purple plastic heart gems and pink/red plastic gemstones (all from Dollar area at Target)
--plastic heart containers (all from Dollar area at Target)
--ice cube tray for sorting and collecting
--random scoopers
--funnels (found super cheap at IKEA)
