Old toys/utensils/tools needed for take apart centre

Hello!  The kids are really enjoying their "hands-on" exploration of pulleys and the ways in which they can make a task easier.  Related to our study of pulleys and gears,  I am creating a "take apart" centre in our classroom, so that students can see how things work and if and how pulleys and gears are involved in the movement of objects.  If you could send in any used toys and/or small objects that we can take apart, that would be great.  Please remove any electrical cords or batteries ahead of time.  Thanks for your support!  Mme Lindsay
