Firstly have the bday in your own home saves tons of money on renting a place & DJ! Download the music or play CD’s. Things you could do would be buy a fix-it hola hoop, play the music & stop like passing the parcel and the one with maximum spins is the winner. This game is enjoyed by parents too as its a tester and each one tries to better it. The same hola hoop can be dismantled and made into a twisted snake, the kids go under it bending who touches the hoop is out, keep lowering the hoop till all the kids are out. The kids out can be made to sing, dance etc as a punishment. Another inexpensive option would be straws give each kids 10-15 straws and set a timer tell them to make the most creative thing they can u will be amazed to see cars, ball & pyramids coming of it. For drinks, serve Tang or Rasna’s cuts out on fizzy drinks price, plus kids have less compared to the fizz and a healthier option too.
