cool toy. Got back from the city tonight. I went to a kids science store and they had a couple of kits that used hydraulics to work.
My short term memory is haywire here, but I think it was 2 syringes hooked together with a thin clear tube. One syringe was fastened at each end to a base and an arm.it was like a small crane made with thin plywood. as you push the plunger on the loose syringe it extended the other one and the arm would go up. It had a red fluid in it,so you could see it work.
At $12.00 it was preety cool. |
