Pom Pom Push- DIY

I made this for way less than the $30+ dollars it cost new.  At 12 months C can't push the pom poms through.  He tries but it requires a good bit of single finger fine motor skill and he's not there yet. Mostly the cat just bats the pom poms around the living room and I have to go searching for them under the furniture every morning. 

Materials are:
2 foot by 1.5 in PVC pipe- get them to cut it for you the length of a toilet ppr. tube
Piece of sand paper
1 Pkg Machine Screws #10-32 X 3 inches Round head combo (comes with 3 nuts for btm.)
Gorilla glue
Screwdriver that is very skinny
Drill Bits (I used .5in, 3/8in,5/16, 7/32)
Blocks to mount the tube on
Large Pom Poms at least 4 (I bought the mixed bag at Michaels)
Wooden Rounded Plaque  9X12
