Puny transformer, will it work?

Hello,
Any input much appreciated.
I am advising a friend on his daughter's science project. He got a 3kv 20ma
NST for free and I wonder whether they are likely to be successful in making
a very small coil. I have never used such a small power supply.
Many thanks,
Robert Hanford
