  In the last two years various existing public outreach activities in ALICE
have been adapted for online usage, this includes the well established particle
physics masterclasses but also virtual visits to ALICE. Based on these
foundations a six month online workshop was carried out in 2021 with the goal
to design a LEGO model of the ALICE detector at the LHC at the scale of a
typical minifigure (ca. 1:40) and to motivate young people for a long term
online collaboration in a particle physics project. The design stage of the
model took half a year with regular online design sessions accompanied by input
on 3D construction, detector technology, the physics questions of ALICE,
virtual ALICE visits, and particle physics masterclasses. This stage provided
first-hand experience on the dynamics of working on different sub-projects in a
research collaboration and resulted in a model with more than 16 000 parts that
was assembled by the participants during one weekend in an in-person workshop.
The experience gained during this construction has been used further by the
young designers to optimise the model over the period of another year.
