The girls needed to make an instrument for science class- and they needed to be able to play a tune on it...which requires distinguishable notes. HOLY CRAP! That's pretty crazy...especially when they only had a week to work on it i.e. finding or thinking of an idea, making it and then learning to play a tune on it.
And we have twins...so I was freaking out thinking that both girls had to come up with two different instruments! Luckily their teacher let them work on it together- they just needed to play different songs. Wphew!
So the twins searched the internet...google- its a miracle machine! Searched "home made instruments" and they decided on a pvc instrument. They can be crazy complex...check this one out! We scaled down the instrument to include only one octave. The girls played Jingle Bells and We Wish You a Merry Christmas. And they received 105/100 as a grade! Can you say BONUS POINTS! :)
