How is your Hungarian (Magyar)? These are so cute and easy to make. In a classroom, instead of toilet rolls you could use kitchen wrap cylinders cut into lengths. These are very simple to make. Even though the instructions are in Hungarian I’m sure you can follow the diagrams and make some of these cute little racers. This could be a great craft afternoon activity for parents when hosting a sleep over or other such social event. Lots of fine motor skills involved here for developing hands.
