One day, walking home from school and noticing this:
A chute
That same day, reading ECE wizard Tom Bedard's blog and seeing that he built a cardboard chute apparatus for his classroom sensory table.
Finally, walked past the school's cardboard recycling bin only to find the most perfect cardboard boxes, one being a narrow chute, which led to this
One side has two tubular chutes that release
into a 5 gallon bucket. The other side has a
long chute pouring into a big plastic bin and
a shorter one pouring back into the table.
