Popping boba diameter

[phandzus]

I tried the spherification/ popping boba experiment. The video shows very small approximately 2 mm boba being created, but then it also shows larger approximately 8 to 10 mm boba . I've tried in vain to find a syringe that has a larger diameter output, but they don't seem to be available (probably because they need to lock with standard size needles). Could you share a method for creating larger droplets and therefore larger boba? Thank you

Hello,

This looks like a fun project! I have not done the project myself but you may be able to cut off the narrow nozzle of the syringe so it has a wider opening to make larger boba? You could also try using other things you have around the house like a straw or a baster?

Hope this helps!

Hi - To add to what Audrey suggested, you mention the video... if you consult the project directions, the materials list calls for a 60 cc plastic syringe. That might help you locate what you need. (You can see what it looks like in Figure 5.)

Is that the size you used when trying the experiment?
