The creation of BECs in dilute alkali gases provides us with a unique opportunity to study quantum mechanical wavefunctions with a macroscopic object. Using a wavefunction engineering technique developped at JILA, the BEC's wavefunction can be taylored. By this means we have been able to create topological structures like solitons and vortices. In our spherically symmetric condensates the solitons undergo a dynamical instability (snake instability) and decay into vortex rings. In this talk the experimental techniques as well as our experimental observations regarding topological structures such as solitons, vortex rings, vortex lines and vortex lattices will be discussed.
