1. compressed baking soda
what material did we use to prevent the cards from slipping on the desk?
towels

When we closed the bottles of Lava lamps and re-opened them, we noticed a mini bomb-like explosion caused by?
The pressure built up from the reaction of baking soda and vinegar
Why was a desk, not an ideal surface for stacking cards
A desk was smooth, and slippery which could have made the cards more easily fall or slip, while a towel provided more stability

simple explanation
An object in motion stays in motion, while an object at rest stays at rest unless acted up by an unequal or unbalanced forced
