watch the eggs. focus on them. don't take your eyes off them. count how many you see and post in the comments how many there were!
is it hard? there's actually a way to do it without counting. shh! don't spoil the secret! thank you to the tv show "Brain Games" (on Disney+, the same show I gett all my illusions from) for showing me this, I guess it's not an illusion, but it's fun!
