because glass and chinaware are delicate substances and can break with a little shock.So,they are packed with straws as straws have air pockets which decreases force and prevent glass and chinaware from breaking

Describe the construction of a kaleidoscope?
Construction of a kaleidoscope:Three rectangular mirror strips of dimensions 15cm × 4cm (l × b) are joined together to form a prism (fig a). This prism is fixed into a circular cardboard tube. The circular cardboard tube should be slightly longer that the prism (fig b). This circular tube is now closed at one end with a cardboard disc. This disc has a hole in it through which we can see (fig c) .At the other end of the circular tube, a plane glass plate is fixed. It is important that this glass plate touches the prism mirrors. On this glass plate, several small and broken pieces of coloured glass are placed. This end is now closed by a round glass plate allowing enough space for the coloured glass pieces to move (fig d).

Can a fresh snowball - if very tightly squished together - break glass?
Yes, but not all glass under ordinary circumstances. Ordinary window glass can be broken by a snowball (I have seen it happen). Plate glass and automotive glass are more resistant to breakage. Also, snowballs sometimes have extraneous objects, such as pebbles, packed into them, and these can break even more resistant glass. All of this depends, of course, on how hard the snowball is thrown. If the person throwing the snowball is moving, for example in a vehicle, or the snowball is thrown downward to accelerate under gravity, or the snowball hits a moving vehicle, even a soft snowball could break resistant glass.
