What you need:

toilet roll middle
ping pong ball (or rolled up newspaper will work)

Fold the flap into the middle
and add a bit of tape to keep it in place.
Turn the toilet roll middle 90° and cut two slits at the other end of the roll, 3cm long and 2cm apart. Hook the elastic band around the flap, push the flap in and hold it in place with tape.
Turn the toilet roll 90° again and make a hole 4cm from the end, repeat on the opposite side. Decorate the toilet roll middle.
Take the box and on the side mark 5cm down and make a hole, repeat on the opposite side.
Push the bamboo stick through the holes the decorate the box.
Cut a piece of straw about 1.5cm long and slip it over the bamboo stick.

Pull the toilet roll back so that the elastic band is tight, pop in the ping pong ball and...
