You can get fusion the way the picture is done - it's just less efficient than a fusor, which is pretty bad in itself.
If the thing is actually the way the picture is, they're just honking two deuterium beams at each other and trying to get some head-on collisions
that overcome the Coulomb barrier. That'll work, but you have worse odds than if you have them happily zipping around trying to get to the center of
the fusor's inner ball and missing.
Another way to do this that'll work for demonstrations is to get some lithium deuteride for a target and shoot it with high speed deuterons or
tritons. That gives you a lot better odds of getting fusion than head-on collision in two beams, unless you've got really collimated high current
beams, which I wouldn't expect a kid to manage.
IIRC, that's the first way fusion was ever proven, too, a deuteride target and some deuterons in a beam.
