I started cooking with both of my kids around two. Find things he can stir to help. Sometimes, if it was a recipe they couldn't help with, I'd crack and egg and let them stir that. Or put water and flour in a bowl and let them stir. That would keep them busy enough while I finished up dinner. Magnets are great. The dollar store carries letters and numbers. If you put magnets on a cookie sheet, they are portable. Puzzles are terrific at this age. I usually buy them second hand from Goodwill, because they can get pricey when you buy them new. If you put finger pain in a snack ziplock bag that mix, red on one side and yellow on the other. He can push it around in the bag and learn about making new colors. Along with the bubble stuff you did, you could practice sinking and floating.
