ball dropper

My son is going to be 4 years old in April 2021, and ever since he started playing on his own he loved things that rolls or drops. Vehicles, balls, fountains, cereal and nuts containers, etc., and I had been recycling cardboards into ball and car rollers all these while to keep him engaged. But he pulls it apart within few days and recently came across a ball dropper set on Amazon and I kind of liked it and got inspired to do this one using Popsicles. 

just added a few fairy lights and he is super excited to play with it.
