This is a clock. You can tell because it's the first thing that comes up when you Google search "clock circuit kit". It is not a bomb.
This is also a clock. Some people might mistake it for a bomb, but it's not.
These are some students playing with circuits. It's pretty widely accepted that technical education is important. Young students interested in tech should be encouraged to build. They are not building bombs. They're learning.
There's a big inclusivity problem in tech too. People just want to create cool things. Race, gender, etc doesn't change this. Certain groups are not more likely than others to make bombs.
Don't stop people who want to create from creating.
