What you need...
A bottle of any kind (The wider the mouth of the bottle the better it is for the younger kids)
1. Sit the bottle on the floor.
2. Have your kidlet stand above the bottle with straws.
3. Now, they get to try to drop the straws into the mouth of the bottle.
ways to do this would be with wooden clothespins for babies. However,
simply have them try to "place" the clothespins into the bottle, rather
than dropping them in.
