    Acoustic Tractor Beam

    I've ordered all the parts for this and plan on building one for my physics presentation this term. I had to order the transducers from aliexpress and am concerned they won't ship to me in time. Does anyone know anywhere that has them in stock? I have all the other parts either here or on the way. I've already 3D printed the bowl at school. I'm located in the United States. Thanks!
